This Princess Sally tee is from Segaworld Sydney. As you can see by the odd proportions, it's a child's extra-small size. Segaworld wasn't afraid to have any character be a solo star on merchandise. This was cool for fans & helped their designs stand out, especially at the time. The shirt just has a happy Sally head with her name "Princess Sally" written in an early 80s & script font at the bottom. The blue & red sleeves are a good touch as well. None of the clothing is common any more, and interestingly, the articles that show up for sale tend to be the super tiny things / girls things that were LEAST in demand while the park was open.
