When I visit Tucson Arizona, I tend to spend a lot of time in the "old town" area near downtown. That's where my favorite restaurant is located and it's also where there are a lot of historic buildings.
The last time I was there, I noticed how each of the doors along the building that houses local arts and crafts has been painted with different designs.
Each one is a unique design.
What a clever idea!
Such an appealing way to attract customers to each of the little shops inside this building.
