The card fronts show a piece of colored artwork, depicting a scene from America's history (and often patterned after a famous painting), captioned at the bottom, with a funny word balloon superimposed over the art. The backs show a fake newspaper front page, with the card number and set title at top, with the card caption (a different one from that on the front) as the headline, and a brief bit of humorous text providing the news story.
Each card in this set also exists as a sticker; the stickers are on thin white cardstock, while the cards are made up of the regular grayish, slightly thicker stock. Each pack contains 1 card and 3 stickers, thereby making the stickers much more plentiful.
Apparently many collectors simply go for the stickers, bypassing the cards entirely.
This set was issued as a test at first, with only cards.
