Colored pencil illustration of Marilyn Monroe by Robert Crumb.
"Robert Crumb had several good friends he corresponded with as a teenager, like his best friend (and future brother-in-law) Marty Pahls. Crumb would add a special touch to each letter by folding the paper in half, booklet-style, and adding a ‘front cover’ illustration. On this ‘Note’ letter, dated Saturday, July 23, 1960, Crumb has drawn a portrait of actress and cultural icon Marilyn Monroe. ‘Don’t ask me to explain,’ wrote Crumb on the reverse side, ‘I did it just to test those new colored pencils that Charles brought home… those pencils are good!’" (via)
