10 or 20 - 4x6" and 4.2x5.5" Postcards, representing tributes to classic artists and albums from the golden era. Postcards are hand-selected at random, but you can surely make requests and I'll do my best. You can also say things like "Classic" or "Underground" or "Add some west coast," stuff like that'll let me know which way to lean in selecting your cards. You can also say "Do not include _____" if you want me to stay clear of certain artist or something. I'll do what I can lol You can order 10 or 20 pack bundles.
