From the amazing NYPL: Cigarrette cards. I love these things. I thought about curating an exhibit of cigarrette cards, but it's probably better to look at them enlarged on the web than it would be to see them behind glass in a frame. These are from the "Colour in Nature" series. The back of each card has a little paragraph of info about each image. I've included a few card backs that I thought were funny, and I've picked the cards I liked the best. But they're all great. You can see the whole series online here.
I love that a Springbok pronks.
And I didn't even put in the three-pronged stickleback!
