Lost set of vintage baseball cards including a Ken Griffey Jr. rookie card and holographic Barry Bonds kept in a protective binder at Riverside Park.

Description

I believe I lost a set of vintage baseball cards while visiting Riverside Park in Sioux City last weekend. The collection includes several rare cards such as a Ken Griffey Jr. rookie card and a holographic Barry Bonds. They were kept in a protective binder that also has some personal photos in it. I really hope someone finds them, as they are my most valued collectibles from childhood.
