First is a couple of PC of the Elysium, which was once the largest indoor ice rink in the world. At one point it was the home of the Cleveland Falcons, which became the Cleveland Barons, before they moved to the Cleveland Arena.

Second is a PC of the Luna Park Entrance. Inside Luna Park was the "Luna Bowl" and also a baseball field. The Luna Bowl was the home to many early professional football teams in Cleveland. The Luna Bowl was originally the "Motordome" which hosted early motorcycle racing. The baseball field was the home to a handful of Negro League franchises.

Third is a couple of PC of Baseball games at Brookside Park. Brookside park is rumored(I haven't been able to confirm this) to have been the location of "National League Park II" in Cleveland. It's also noteworthy for having held the record for the largest attendance at a baseball game in 1914.(If I remember correctly it was mentioned in Ken Burns' Baseball)

Finally, a PC of Municipal Stadium postmarked 1935.
