But is is Art???

So most of you know of my father's crazy collection of corruptions of great works of art. Funny Mona Lisas, poor reproductions of the Venus de Milo (does that make his a collection of Veni de Milo??) and all of the Last Suppers, from the sacred to the profane. So he and Erin are up in his 'artist studio' the other day where they often go to paint, glue, collage (is that a verb??) and Erin stated that instead of painting the Last Supper, she wanted to paint 'The First Supper.' Which got me to wondering, what other revisions could you do -- Monet's Pond Scum, Winged Defeat, Van Gogh's Mostly Cloudy Night -- the mind boggles at the possibilities!
