24 X 30.
Arches Cover Paper.
The photograph makes the angles of the far windows look slightly distorted, I sort of like it. In reality, the lines are straight and you don't see any waviness.
The photograph below was taken by Robert Meier who I recently had the pleasure to meet. Meier is a professional photographer who produces brilliant work. He has a show right now at the Hopkins Center for the Arts http://www.hopkinsmn.com/_hca/exhibitions.html
His work can also be seen on http://mnartists.org and search for Robert Meier
