This was done on a night tour in the Cathedral of Mont St. Michel in Normandy. At some point in the tour, some paper and some stamp were provided, mainly for small children to enjoy. Stamps were based on the theme of the tour where various bird images were projected on the walls and ceilings of the cathedral. So I joined the children to paint my own bird.
I had an empty frame at home and was looking for something that fits. When I have folded the bottom it fits perfectly.
