Unearthed (so to say) from my stamp collection are two blocks of unused flying reptile and dinosaur stamps. These 25 cent stamps were issued by the United States Post Office in 1989. I covered each stamp in its cancelled form earlier in the year. It was educational for me, as I learned the difference between a dinosaur and flying reptile. An added bonus was learning about issues with the Brontosaurus stamp.
