A framed print of The Old Guitarist by Pablo Picasso from his Blue Period, hangs over the mantel in the Steven's living room on Bewitched. Oddly the picture is hanging on its side, perhaps to fit the available space. Picasso was still living and working on his Chicago Picasso sculpture around the time when the picture was seen on the show. Although Pablo Picasso never visited the United States I wonder if he knew his print was hanging sideways on the popular TV show Bewitched.

From Wikipedia:
"The Old Guitarist is an oil painting by Pablo Picasso created in late 1903 and early 1904. It depicts an elderly musician, a blind, haggard man with threadbare clothing, weakly hunched over his guitar while playing in the streets of Barcelona, Spain. It is currently on display at the Art Institute of Chicago as part of the Helen Birch Bartlett Memorial Collection" https://en.wikipedia.org/wiki/The_Old_Guitarist
