I first heard of Angelina Ballerina by Katharine Holabird through the animated series. We were in Bend, Oregon on a trip. Harriet was getting over a stomach bug and I was coming down with one. We were holed up in our hotel room eating take out and watching kids television. Harriet was just learning to walk at the time. I don't know if her first exposure to Angelina Ballerina made any lasting impression or not.
