We've got a painter, oops, artist, doing a mural on the side of
our building.  It's a 50's or so type of art work.  It is about
the time frame that the artist grew up in.  Based om the cars
he drew in, 1954 or so...

A kid (sorry, but I don't know how young) comes up to him.  The
kid asks, "I like art and I'd like to be able to do what you
are doing.  How did you get those old scenes that way?"

Artist:  "I did it from my memories as a kid."

Kid:  " I didn't know memories lasted that long..."
