Lost postcards near Gateway Arch, St. Louis

I lost my stack of travel postcards from last summer around 5:20 p.m. last Friday near the Gateway Arch, by Market Street and the riverfront. I had been at the City Museum gift shop earlier and then walked toward Arch Park when they slipped from my tote. They carry memories of my grandmother's handwriting and a few stamps from foreign trips, so I feel a bit overwhelmed and hopeful. I retraced steps along the riverfront and asked a few street performers if they'd seen a notebook, but I haven't seen them since. They are small keepsakes I can’t replace, and I’m hoping they turn up where I last set them down.
