A week ago my dear old dog and friend Marcus passed away. He was a spirited, ornery as hell wire haired fox terrier who had been a close part of my life for 17 years. My wife and I called him one of our “protochildren” (along with two cats), our kids before we had kids. I’ll miss him dearly! If you look at many MANY of my old paintings and illustrations, you’ll find him.
So right before I turned in the final art for Field Trip to the Moon, I had an idea for an alternate cover. It featured the class and space station more, and the bus less. Basically I just really thought the station should look like it spins to make artificial gravity. The editor passed on it, which I agree with, but I still like the way it looks.
