Back in November of 2014, I gave Col. Chris Hadfield a painting I did. It was inspired by his book: An Astronaut's Guide to Life on Earth, which I got a signed copy of.
He also shook my hand so hard that it bruised slightly. I didn't mind in the slightest. :)
Unfortunately, I couldn't be there in person, but I was at Gallery Hittite in spirit, celebrating the Christmas group show, along with the many talented artists, such as Sara Caglar {gallery owner), Anna Zinato, and Cem Basarir.
