As you can see, it includes a colorful sleeve with drawings done by Nicholas Volpe -- known for the various player portraits handed out by Union 76 over the past several decades. Furthermore, each sleeve includes a portrait drawing of Vin Scully. Each record has a separate Scully interview on each side, and fans were able to purchase a single record at participating gas stations for $0.49 each with a minimum purchase of gas.
On the right is a advertising poster for the records that had been previously shared by Mark Langill at Dodger Insider (link here). Apparently, the poster is thought to be the only copy in existence today.
As for the records, I don't have any recordings to share. If you happen to know where I could listen to any of them please pass that along to me.
