These (well any one of them in this shop actually) vintage biology pull down charts are on my wishlist. Check out this Etsy shop, it's glorious!
I'm partial to oceanic critters.
Insects are cool too!
I would probably give my left arm for one featuring an Octopus or Squid, though that might always be a dream as they are hard to find. One day I would like to have a collection of these hanging on my family room wall.
Do you have any special items on your wishlist? I'm going to head over to The Colorado Lady then day dream a little more about my biology chart gallery wall...
