During the 80's I taught several classes at the Smithsonian. One class was Soft Sculpture probably made popular at the time because of Claes Oldenberg's work. I created the hamburger as a kind of sampler for the class. Each layer of the hamburger was a different technique. A stuffed and painted bun, with the bottom half painted with red paint (ketchup), the tomato stuffed and quilted, the slice of onion was severa layers of white organza stiched in circles, The Swiss cheese slice again was quited with holes. The actual hamburger was brown fabric stuffed then covered with brown yarn crochet. Lettuce leaf was several layers of organza stretched as it was stitched with various greens so it ruffled. The potato chips were a couple of different colors of organza stretched as they were stitched, turned inside out and pressed. The olive was another stitched and stuffed shape. I don't remember when it was sold but could have sold several more if I wanted to create more. I didn't.
