The dish is probably USA or Japan made, but there is no maker's mark. It just screams retro, both from the motif and the colors. I was in a home just this week where, when you walked into the family room, you went back about 35 years. It was a wonderful experience.
The sundae is banana and pineapple, with dark chocolate sauce and a maraschino cherry for color. No strawberries, or it could have been a banana split.
Repurposing your favorite dishes is so much fun. I'll keep this soup mug for chili, goulash and ice cream!by
