1960s stamp album with red leather cover

Yesterday around 3pm at the Seabreeze Market along Oceanview Street in South Coast, I was chatting with a seller and flipping through my 1960s stamp album. It’s a red leather-bound collection with glassine pages, and inside are stamps from Japan and Germany plus a couple with perforation errors that make it special. I left it on a small folding table by the coin booth for a minute and when I came back it was gone; there was a faint coffee ring on the inner cover as well. It means a lot to me—it's a gift from my grandfather that sparked my hobby, and I really need it back.
