Hi all,

I've been looking through my late Grandmothers' autograph collection this evening. I've had it for several years and one of my favourites is an autographed photo of Marlene Dietrich, with a handwritten envelope sealed with a stamp gearing her caricature. Over the years I've had a look at other Dietrich autographs but my one seems a bit different. The envelope is postmarked 9th Feb 1975, London which would match when she was there doing concerts. My Grandmother wrote to her to get some autographs for a charity auction, I think this arrived too late though. Any thoughts as to whether it could be authentic or not?

Thanks

Katie Jones
