Artifacts of two of the greatest pop-culture icons of your generation have just hit the auction block.

After nearly 50 years of being hidden away in a basement, a collection of never-before-published photos of the Beatles by photographer Mike Mitchell were auctioned at Christie’s on Wednesday, CNN reports. The black and white collection sold for $361,938, and the silhouette of the “Fab Four” for $68,500.

Meanwhile in Buenos Aires, one of the only two known copies of an alleged porn short film starring a yet-unknown Marilyn Monroe is going up for sale. The starting price: A mere half a million dollars. The controversial black and white six-minute film, shot sometime between 1946 and 1947, is hitting the auction block because the Spanish collector who owned it recently passed away.
