1960's Chicago Cubs Sleeve Patch Game Worn??

[gameon]

I bought a 1960's Cubbie Bear sleeve patch years ago. It definately was worn and washed and detached from a Cub uniform. I dont know enough about the actual size of their sleeve patches to know whether it came off of an actual MLB jersey or another type of jersey. Ive added some pics to show the actual shape and size of the patch. Any help would greatly be appreciated. Thanks, Gary
