You are looking at the wrapper to an oddball set made by Donruss in 1978 called "All-Pro Skateboard!" This is vintage wax at its finest. Each pack contains 5 sticker/cards and 1 regular sticker. The set contains 44 total pieces, including two unnumbered cards.
The fronts of the sticker/cards, er the "sticker side," features some groovy skateboard-related imagery, text, and sayings. The sticker/card number is generally featured in the lower right corner:
The sticker side features a peel-and-stick that is roughly die cut around the text and image, though not necessarily tightly so.
The "card side" of each of the sticker/cards features some of the shoddiest photography I have ever seen on a card. Wow, there are bad. The shots feature the specified skateboarder in action alongside a border on the left and right composed of red and blue lines. Below the image, red text details the person's name. age, team, specialty, and other related info. Beneath that, black text gives some history about the person. Here, we have Stacy Peralta, Russ Gosnell, and Steve Schissler:
The images in this pack are fairly bleeding, giving them an almost 3d (red/blue) effect. The pure sticker has nothing on the back. Not sure why they decided to make some with nothing on the backs. We have Dave Dillberg and Ed Nadalin:
