Tucked inside a 7” box set boasting the phrase, An Album from THE TREASURY OF IMMORTAL PERFORMANCES “45” rpm, this Capitol Records insert informs the 1940s (possibly 1950s) buyer of the intricate do’s and don’ts of optional center record care. This clear-cut informative guide urges the following, with extreme, underlined importance: If you will be using this album on a large spindle 45 rpm player, Ask Your Dealer To Punch Out The Centers… I don’t know about you, but my dealer doesn’t know jack about anything record related, but lucky for all involved, these “optional” inserts have long since been removed, so any sort of option has been swiftly eradicated.
