Entitled My Wife’s Lovers, by Austrian artist Carl Kahler, the work is estimated to sell for $200,000–300,000....“The picture is so large and so heavy, we had to make a special wall to hang it; when we originally put the painting up on a normal wall, it pulled the nails right out of the wall.” ...The behemoth work dates back to 1891, when San Francisco art collector and cat lover (obviously) Kate Birdsall Johnson commissioned the Austrian artist to paint her 42 cats, (rumor has it she owned anywhere from 50 to 350 cats at any given time, and they had their own floor in her Sonoma County mansion). There is no concrete evidence as to how long it took the artist, who had never painted a cat before, to create the work. But it is estimated that it took over 3 years, for which he was paid $5,000. The title is attributed to Ms. Johnson’s husband, who obviously had a dry sense of humor. [https://news.artnet.com/market/is-sothebys-selling-largest-cat-painting-350447]
