Thank you Iain. The only thing I can think of how the concept came was just my surroundings where my studio was located. It was in a predominantly Latino neighborhood, where I've lived in most of my residents, but this studio (at the time) was set pretty deep into the culture. You'd see an extraordinary amount of art, murals, and Day of the Dead celebrations were a big todo. Ofrendas stood in people's businesses at times, out on the street in their gardens, etc. My parents died just before I got the studio there and I was paying respects to other people's family. It made me want to make something like it for them, but I am not Mexican and felt weird doing it, so this was my way of doing it--paying respect to them in a painting instead, based on an alter.
They were both bowlers, and they both had love of certain snacks, and that's what's usually on the alters, sometimes loose change, other "toys," lots of flora, flowers, candles, etc. They're face are drawn like this because it's how I always drew them, as caricatures, because they were.
