Dinosaur Cards
Playing cards come in all shapes, sizes, and designs. Especially in recent history, it hasn’t become uncommon for novelty packs to crop up with their own identifying characteristics. This particular playing card is from a deck about dinosaurs, as the image on the card suggests.
As for the writing on the cards, it’s actually just facts about dinosaurs, not rules for a game. It includes plenty of classification information as well as facts like its average height and weight.
