Added today are cover scans of a 1951 company sleeve, providing information about the new (Minigroove) 78rpm format for record dealers (more specific: Decca dealers). The sleeve I have, was used for Philips P 01003 S, but it was used for other early 78rpm titles as well. Click on the image below to go to the page of Philips P 01003 S, which shows all sides of this gatefold sleeve and provides more information.
