Need help identifying this--Babe Ruth/Yankee Stadium

1966CUDA

Just wondering if anyone knows the origin of this postcard??? Also wondering if PSA would grade?? I checked the SGC pop. report and they show a "1920's Yankee Stadium" postcasrd as being graded but they did not label it as having anything to do with Babe Ruth, who is clearly on the front? Any help would be appreciated. thanks-Claude (I do know PSA does grade some postcards: '68 Dexter Press, 1908 R.C Williams Cy Young..just want to identify this one to see if it can be graded/authenticated?)
