The longest-running series of those created by writer/artist Sheldon Mayer is this one, which began in 1956 and ran to issue #98 in 1971. Larry Nadle was probably the editor technically, but Mayer was a former editor at DC himself, and didn’t really need one I’d say, except to traffic the lettering and coloring. Mayer clearly had plenty of ideas for these two very young children and enjoyed writing and drawing them. Even after the series ended he continued to make more, and DC paid him to do so. Some appeared eventually in America, while others were only printed overseas. The two tykes are neighbors and friends, but Sugar was the leader and idea person, while Spike usually took the blame for her naughty ideas. They could speak to and understand each other, but to their parents, what they said came out as nonsense, while the kids couldn’t understand adults either. This led to many funny situations.
Ira Schnapp designed the logo, using thin serif letters and two large S’s to make space for character heads by Mayer. This cover of the first issue got right to the storytelling with a four-panel gag lettered by Ira. Note the more wavy edges to the balloons in the first panel where the kids talk to each other. That would become more pronounced. Mayer often did the balloon shapes, as he did here. A few other covers had four panels, but most had a single image. Schnapp lettered many of the covers and inside pages in the book until issue #76 in 1968.

The cover of issue #2 is a typical example of Sugar being bad and Spike taking the blame, a theme many kids could probably appreciate and find funny. This was the only DC series focused on very young children, but the humor might appeal to any reader who tried them.

Issue #4 is a more typical single image gag, but Mayer’s art and humor told a complete story all the same. Here Sugar’s speech balloon is completely normal, so added by Schnapp. Mayer would have made it wavy.

By issue #8, the child-speak balloons were completely unique, using upper and lower case lettering by Schnapp in a balloon with scalloped edges and tail. Ira has done a new version of the “You’ll Like” tag.

On the cover of issue #10, the adult balloon is rounded, and note the water drops around the first two words. Sugar’s balloon is in the new style, and you can see here that the tail edges criss-cross, while her words are upper case again.

Issue #17 from 1958 is back to upper and lower case Schnapp lettering, but the balloons are by Mayer. I don’t think either of them were too concerned about being consistent, as long as the humor worked.

Issue #21 saw the first appearance of a new Schnapp logo using thicker sans-serif block letters in a wide oval shape with the names on two lines. I think the character heads are the same. The background of reversed images is an unusual treatment for this book.

On issue #33 you can see that Ira’s outlines for the new logo were quite thick to help readability against a busy background. His script on the candy box is elegant.

Many of the six yearly issues had repeated themes, here’s another Valentine’s Day one. Other themes included summer vacation, Halloween, and Christmas.

On issue #55, the lettering is back to upper and lower case in a wavy balloon for child-speak in this Halloween gag.

Another Valentine cover for issue #63 goes back to standard Ira Schnapp upper case lettering for the child-speak balloon, and features two large captions. There was plenty of room for them.

Schnapp’s final cover lettering was on issue #76 from 1968, though I think he did only the child-speak balloons and the bottom caption with the rest being by Mayer. It was a partnership that always worked well.
Here are the covers with Schnapp lettering: 1-11, 13-14, 16-19, 22, 24-56, 58-59, 61-76. That’s 69 in all.

The first page of the first issue shows how Mayer and Schnapp worked together on the lettering. Ira did the caption and balloon letters, while Shelly did the balloon shapes and title and also the big open letters in the burst balloon on the bottom row. Clues to Ira’s involvement are the small, square lettering, the angular S in the emphasized words, and the clincher is the distinctive Schnapp question mark in the last panel. In many cases, Mayer may have turned in inked pages with just the lettering needed by Schnapp pencilled in for Ira to follow.

On this page from #20 are examples of the way adults heard what the kids said in panel two. Mayer explains in the adult balloons. The rest of the Sugar and Spike balloons are in the child-speak style.

For a while, starting with issue #44 above, Mayer asked Schnapp to do the upper and lower case style for child-speak in the stories too. That would have taken more time, and it was only used until issue #56.

In the last few issues he worked on, Ira made another style change perhaps requested by Mayer. His usual question marks were replaced by more standard ones. Sometimes he forgot and did the old style, as in the second balloon in panel six here in issue #74.
These are the stories lettered by Ira Schnapp. He also worked on many of the short filler pages by Mayer like the Pin-Ups, which were actually paper dolls. In some cases, like the Write Your Own Comic pages, Ira only did a small amount of lettering, so I haven’t counted those, particularly since some of them might be repeats. Often Mayer did some of the lettering himself on filler pages, so it’s less clear what Ira did. I’ve only listed the ones I think have a good amount of Schnapp lettering. Especially on early issues, stories not lettered by Schnapp are probably lettered by Mayer. Almost all longer stories feature Sugar and Spike, I’m using sometimes shortened story titles.
