This card claimed to have been signed by Andy Warhol muse Edie Sedgwick recently sold on eBay for $300. In my opinion, it clearly isn’t authentic. Authentic exemplars of her signature are rare and forgeries even rarer. Her original AFTRA card sold through RR Auction for $1,789.

This is from the auction description:

This is an antique original great birthday card signed by Andy Warhol star Edie Sedgwick. It is rare to find her signature anywhere. So this is an opportunity to have a vintage piece of Hollywood history.

My uncle often prided himself on finding the most elusive and scarce photos and items of the old stars that he could. So this is truly a rare opportunity to get a nice card of Edie's signed.

Here’s the card that sold on eBay followed by the signature portion of a card she wrote to Warhol in 1968. I'm surprised that the birthday card actually sold.
