As someone who is always on the hunt for large-scale art at a small-scale (read: free) price, I am bookmarking, tagging, blogging, liking, sharing, and obsessing over this Biodiversity Heritage Library with over 150,000 high-res files for download. You want a botanical print? Check! Birds are more you’re thing? You got it! Fossils? Done! Check it out and thank me later.
