I inherited a similar album of photos (from the 1920’s-40’s) from my father which contained many family photos. As it was a personal item I did not have qualms about removing photos (moistening the black paper with water for several minutes – the photos readily peeled off). Several of the photos had writing on the back which identified people and events which I found valuable. I dried the photos between blotting material under heavy books to ward against curling. The effect was excellent.
