Vintage Purple Knott’s Berry Farm T-shirt – Size Large Youth – This is a purple t-shirt from Knott’s Berry Farm in California with a stagecoach on the front. It is 50% Cotton & 50% Polyester and is labeled a size Youth L. It measures about 15 inches across from armpit to armpit and about 20 inches long from neck to bottom. It was my daughter’s when she was little in the late 1980s or early 1990s and still seems to be in good shape.
