Teri Horton, who bought the painting as a gag gift, was later the subject of a documentary Who the #$%& is Jackson Pollock? that followed her unsuccessfulattempts to authenticate the 1.7-by-1.2-metre paintingin America's auction houses. When it was authenticated later by a Montreal expert, Horton decided to sell the painting through a Canadian gallery, where its value was estimated at $50 million.

"Do I personally think it's worth [$50 million]? Hell no," Horton said in 2008."It's worth the $5 I gave for it. It's ugly."

The painting remains for sale.

Itremains unclear how the painting wound up in the garbage.

Ancient artifacts

A New York junk removal operator found ancient Mexicanartifacts five years after he brought them home in a barrel he thought was garbage. The 60figurines, bowls and jugs were made between 300 B.C. and A.D. 500, according to a New York Daily newsstory in 2009, and remained in storage in a warehouse for years before the barrel was opened.

The estate of a SoHo artist paid thejunk removal company to clean out the artist's apartment after he died.

The artifacts were reportedly valued around $16,500 in total. Nick DiMola, who runs the junk removal company, donated several pieces to be auctioned off for charity.

Centuries-old violin

The tale is a bit convoluted, and there's a bit of family lore involved, but in the 1970s, a woman claimed to have founda violin case on a California freeway. She passed it onto her son, who gave it to his wife in a divorce settlement. In the 1990s, it wound up at a repair shop, where a dealer recognized the Stradivarius inside and found it was listed as stolen from the University of California, Los Angeles,according to a 1994 story in the Wall Street Journal.

A UCLA violinist lost the violin,known as theDuke of Alcantara,in 1967when it was either left it on the roof of his car orwas stolen from the trunk in 1967. The instrument, one of about 600 that remain, was built in 1732.
