Collectors know these artful 6" x 8" cards by three terms: T3s (catalog number), Turkey Reds (associated tobacco brand), and, more generally, "cabinet cards" (for their large and presentable size). This bigger surface meant more chances for damage--note several dings and marks on its "frame"--but there's no denying their appeal. I'd even call them "classy."
Turkey Red backs show the entire checklist, a mixture of baseball players, on-field action shots, and pro boxers. Individual panels start around $100 and HOFers cost much more, so building a complete set takes real money and dedication.
Value: Low-grade Crawford cards run a few hundred dollars, given his HOF status and popularity with Detroit fans.
Fakes / reprints: Several T3 reprints exist and there's no doubt people faked the most valuable stars. Modern companies also adapted the painted look for 21st century players, one of the best throwback designs to choose from.
