It's a city-wide celebration in honor of International Day of Happiness (March 20th) and Mental Health Awareness Month (May).
Below is a slideshow of the hats in the window.

I used 2 large canvasses I painted with big strokes of the official yellow of #INTOyellow to give the display height and depth.
The artwork is prominently displayed in the front, and the rest is yellow hats!
