Are you in need of some dates? Well, you're in luck. Here's some fun for crafting from my ephemera stash--vintage (1960s) library book due dates stamped by the hands of school librarians on the front piece to "A True Book of Plants We Know."
Enjoy using this in all your work, just don't sell or redistribute the original work as your own. Leave me a sample of your art in the comments if you find a fun way to put this work!
