Vintage stamp album with red leather spine

Found this vintage stamp album this afternoon around 3pm in the parking lot behind a small antique shop on 16th Street in Rock Island, Western IL. The album has a red leather spine with gold lettering that’s worn, and the cover shows a few scuffs. Inside, there are stamps from the 1920s to the 1950s, including a block of German stamps and a tiny pressed flower tucked between pages. On the back cover is a bright green sticker with the number 27 and a slightly bent corner. I imagine it means something to a real collector, so if this belongs to you, I’d be happy to return it.
