Green stamp album with 1950s-70s U.S. issues

Yesterday around 3pm I realized my green stamp album was missing. It’s a compact, leather-bound binder about the size of a paperback, with a gold-embossed label on the front that reads 'Boise Philatelic Society.' Inside are around 120 stamps from the 1950s to the 1970s, plus an old pencil inscription on the inside cover: 'Property of Priya Patel.' There’s also a small coffee ring on page 10. I last had it near the Boise Public Library on Capitol Boulevard, by the main entrance and bus stop. It’s more than just a hobby—this collection has sentimental value and I really need it back.
