Extremely rare promotional package for ‘Break On Through (To the Other Side),’ the first single from The Doors, which was issued by Elektra Records in late 1966 in conjunction with the release of the band’s self-titled debut album and their appearance at the Fillmore Auditorium in San Francisco, California, on January 6, 1967. The package is comprised of a mono album proof cover for ‘The Doors’ debut album, with the interior featuring a taped 45 RPM single record for ‘Break On Through (To the Other Side) / End of the Night,’ and the adjacent side bearing an affixed concert poster, with psychedelic lettering that reads, “Elektra Records Introduces The Doors, will open with Sopwith Camel and Young Rascals,” and caption to lower border: “The Doors will open at 8:30 for all who present invitations.” Next to the single record an Elektra representative has added a note in black felt tip, “John: See you Friday, Thanks, Pete.” In fine condition. Elektra produced a very limited number of these packages to promote the band and invite press and retailers to witness the Doors’ Fillmore debut performance; this is one of a very small number to have survived.
