I found these pictures that my dad drew for Steven in an unpacked box (from when we moved here) in our basement tonight. This picture shows what Dad loved to draw the most, ships. He loved ships and being on the water.
This one must have been inspired by Steven himself. Steven used to be a lover of chimneys and pipes, and it looks like his grandpa was playing on that. I can just imagine how intrigued Steven was as he watched his grandpa draw this for him.
