Collection of Decca Records Ace of Diamonds
These 3 records are part of Decca's Ace of Diamonds series. These were produced after the SXL series as a cheaper release using the same matrices as the SXLs. Most Ace of Diamonds releases were republications of existing SXLs, and some earlier examples were actual SXL vinyls that had not been labeled yet.
The Ace of Diamonds logo on the label makes clever use of the diamond shape acting as the bridge on the capital A.
