According to Variety, the silkscreen artist passed away Wednesday, August 6 at the age of 93. He lived in Los Angeles, where in the 1950s he built his open Highland Park home in which he lived until his death.

Known for his UPA animation, Weidman's cartoons appeared as background for The Boing Boing Show and The Famous Adventures of Mr. Magoo.

Most recently his work had found a home on the critically acclaimed Mad Men when set decorators adorned the walls of Peggy Olson's (Elisabeth Moss) office with his work, which can also be seen in different rooms throughout the ad agency.

"The style is very distinctive and indicative of that era and the popularity of Danish modern," noted the drama's set decorator Claudette Didul in regard to Weidman's work. "They remind me of pictures I saw growing up and seemed in keeping with Peggy's sensibilities and reflect her younger and somewhat more cheerful outlook."

Married with three children, Weidman attended the Jepson Art Institute and worked in Los Angeles for over 50 years.

The artist's work will likely continue to hang in the background on the AMC series during its final episodes.
