Years ago, I was in my second year, AP art class, working on a concentration that had boots as the recurring theme. One of my pieces was a duck wearing rain boots that I actually made into a rubber stamp, with which made real life prints. Here's a photo of the piece I turned in:
A little while ago, I managed to vectorize the stamp and am sharing it now. I think any of these would be adorable in a nursery or kids room.
