New Family Heirloom

There's a running joke in our household that I am like Ernie and Davis is like Bert, so when I ran across this puzzle of Bert playing the accordion (Davis' favorite instrument) I had to get it.
But what's one to do with a puzzle when you're not puzzle people? Turn it into a mock family photograph. A few hours of photoshopping is a small price to pay for an "heirloom".
