Found vintage stamp collection near Langley Market

I found a compact black three-ring binder about 9x11 inches stuffed with a stamp collection on a bench outside Langley Market on Whidbey Island this afternoon around 2:15pm. The binder is labeled 'Scott' on the spine, and inside are stamps from the 1910s through the 1940s—mostly U.S. and Canadian issues—still fairly well preserved, though a few pages show yellowing with age. A small enamel pin shaped like a green lighthouse is clipped to the binder, and there’s a faint sticker inside that reads 'L. Chen Stamps' as a possible owner clue. It’s a neat, sentimental-looking bundle, and I’d love to help reunite it with its owner if you can reach me.
