Going to try a little deduction and then make a broad guess... So, painted on wood siding, maybe on a sign. Thinking maybe Frontierland or Liberty Square. But also possibly at the outpost shop in the Canada Pavillion.
Okay, so at MK but not In the Old West or Colonial times... I'm thinking then that an Adventure lies ahead. Maybe I should wait in line for a cruise to find Dr. Schweitzer and the backside of water.
It's really a matter of thinking like an imagineer and picturing where something feels like it belongs in the theming of the parks.
