I was going to leave this as a response to your Discourse question, but I thought it might be OT. Anyway, your question (and explination to the challenger in her journal) made me curious and I looked up the original Stuart Davis piece that Callum is paying homage to. If you haven't already seen it here's the painting. I think Ray would probably like Davis' art. It's very musical being from the Jazz age. Although, being a car guy we know why he got the tat. :D
