At Vintage Printables, I found a bunch of cool prints that I wanted to share with you. (Click them for the full-sized image and to download, save and/or print, free of charge.)
I think this would be cool in a little kid's room (even though personally, the circus totally freaks me out).
Speaking of little kids' rooms - check out this old liner from a Beatrix Potter book with illustrations of her characters! I loved Beatrix Potter as a kid. (Although now that I think of it, I think some of her stories freaked me out, too.)
And, on the opposite side of the clip art spectrum, here we have a viking wrestling a bear. I wonder who will win the match...
A vintage boat advertisement, circa 1927.
