In 2004 Christie's Australia was auctioning off a poster that was originally printed to advertise the Warhol/Basquiat collaboration show party at the Palladium in New York on September 14, 1985.
The poster was never used because of a spelling error ("addmission"). A set of ten was produced before the error was noticed and the poster they were offering was one of the ten.
The poster was to be sold with the actual boxing glove used for the image on the poster. The pink glove was signed and painted by Warhol, possibly making it more valuable than the poster.
The poster and glove together were estimated to sell for $1,000 - $1,500 Australian dollars. The sale was part of their International and Contemporary Paintings auction held August 23-24, 2004. The lot number was 273.
