Ha! Several of you were SPOT ON! Yes it is an egg timer! The wind-up kind. Ours sits on the stove top gathering grease and dust... I wasn't feeling great when I painted it, just kinda wanted to paint something simple and it seemed to fit the bill.
And this is Boone! for Dede, from my incredible Door County Adventure! Feels so good to PAINT!!! I hate when I get too busy- and I DO LOVE commissions! Because they MAKE ME PAINT!!!!
