Please share opinions regarding the Ansel Adams signature of interest on the postcard in the image below. I have also included an image of two postcards from the RR Auction archive for comparison. To my eyes, the signature on the single postcard is pretty close to the signature on the top postcard from RR Auction. However, my record of authenticating has not been too good as of late so appreciate feedback and comments from members with more knowledge and experience. Thank you as always.
