Viaduct?

Vy not a duck? Only observant Marx Bros. fans will get it, but if I don't have a song title to allude to, I'll steal a line from a movie! Anyway, this is Eddie, one of those millions of ducks with name tags that have been sold over the years. I think we got this one in Carmel. I left his name tag off, does that make it a nude portrait?
I had been working on a more difficult painting and needed to take a break and make this sketch.
