I made this poster a few years ago and it just occurred to me that I can share with you all here. A-Z Rock Poster I made it a project to paint one rock for each letter of the alphabet. When I was done, I arranged them all in a single image on photoshop. This whole process took me about 4 months. I am currently making a "minerals" poster. I'm at the letter 'Q'. Tell me some rocks you'd like to see me paint!!
