These are six Steinweiss designs on Decca in DL10000 numbers. They seem quite a bit later than the previous posts. The backs read Decca, a division of MCA, Inc. According to
this should date them to 1966 or later. These are clearly Steinweiss, and show a real comeback to me. I find these late 1960s Decca records to be wonderfully inventive covers, not as beautiful as the golden age 1940s sets, but still great stuff.
