Gah! I saw one of these on Pinterest yesterday, and I desperately wanted to know who the artist was… but I’m not sure that I’ll ever know. A few clicks on that pin, and I found this entire treasure trove of vintage geological illustrations! They are part of a collection on Vintage Printable, under the category of Gems and Minerals. Pages and pages from old textbooks, that are now part of the public domain. All of you collage artists out there know what that means… yep, you can use these images for whatever you like! Time to get the scissors out people.
i’m jealous of old rocks
