The only thing I didn't love about Bill's paintings was that he loved to sign his name really big in red paint at the end. I always thought that messed up his paintings. LOL I also watched Bob later and at the time didn't know there was any controversy between the two. Bob definitely was more popular than Bill, once he got started.
Oil paintings can last forever, but I wasn't particularly good at it and didn't do it long enough to get better. I kept the paintings for a number of years, but eventually let them go. I didn't paint steady till I was much older, but I didn't use that style when I got into it more.
I was fun watching and trying it, back in the day.
