This photo is currently up for sale on eBay.* It appears to be from the Hollywood premiere of The Gold Rush.
Douglas Fairbanks and Mary Pickford are at far left with Gloria Swanson. I'm not sure who the women are on either side of Charlie. That might be Norma Talmadge at far right. Someone more knowledgable may be able to identify them. I think there is something a little fake-looking about this photo. The background looks airbrushed out. Or it could be a composite of individual photos from the premiere.
*The eBay seller lists Paulette Goddard as being in the photo. Of course, she is not. And the photo they include of the back is for a different picture.
