Vintage ceramic Sunny Manitoba mug made in Japan

This is a cool Manitoba souvenir with a map in half of it showing lots of towns around the province. A lovely vintage yellow in excellent condition with the exception of one tiny chip near the rim (see photo). I’m leaving but as-is but if I were going to display this mug myself, I would touch that up in a heartbeat with some brown sharpie or nail polish. I pack and ship breakables safely.
