Cover: Temporary paper envelope / sleeve. Larger than a standard 45 RPM sleeve, reminiscent of a mailer envelope. Coated paper stock. The back may contain a glue strip on top. The paper fold is glued over the bottom and there is a seam along the middle of the back.12
This is an example of mystery mailing envelope. It was offered by Heritage Auctions and ended on April 27, 2014 without a sale, as it did not meet the reserve. It was misidentified to be for the CR-15 Old Shep custom record, which has thoroughly been dis-proven. The back may be compared to the envelope used for EPA 747 for similarities. The artwork is by Will Eisner, a comic book artist most notable for The Spirit. This example is addressed to KVSO radio in Ardmore, Oklahoma. The postmark is December 21, 1956. It could be inferred that the record was produced at the Rockaway plant as the postmark is from Rockaway, NJ.
