Here are three different versions of "Three on a Soda," done by arguably the three most important Archie artists in terms of setting the house style that all succeeding them (or in between any of these two artists, anyway) would follow. The first one is from Archie's co-creator, Bob Montana:
The second one is from my personal favorite, Harry Lucey:
And the third one is from that most well-known of Archie artists, Dan DeCarlo. It was this version that got put on a postage stamp a few years ago.
Here's Dan Parent's version, from Archie 647.
And Stephanie Buscema's variant cover for Life With Archie 31.
Check out the cover to Jughead #215! Rex Lindsey does his version of "Three on a Soda"!
Here's Adam Hughes' variant cover to Life With Archie #36, the "Death of Archie" storyline!
This was drawn by Gisele for a gender-bender of a storyline.
And this, again, was drawn by Gisele, this time for the Archie/Predator crossover.
Here's a variation of the theme, with Dilton in the middle. I'm not sure who the artist is, but I think it was Bill Golliher.
