Red leather stamp binder with rare misprint stamps

I lost my red leather stamp binder yesterday around 3pm near Fountain Square Park on State Street in downtown Bowling Green. It's a compact red binder with a cracked spine, filled with 1930s-1950s stamps. Inside there's a misprint on a 1939 Air Mail stamp on page 14 and a small green sticker with the initials MP on the inside cover. The binder is in decent condition overall, but the spine is clearly cracked and the pages are slightly foxed. This collection was passed down from my grandfather and holds a lot of sentimental value; I really need it back. If anyone found it, please drop it off at the Bowling Green Public Library or message me here.
