There is NOT a Capitol Record Club version.
Goldmine Price Guide is wrong, no big surprise
Longinnes had no interest in selling a 3 record set, when they were trying to sell the 3 individual LPs.
There is NO evidence anywhere that a version with a Blue Spine ever existed,
No-one has ever seen one, or ever will, on account of there were never any made
The Capitol Record club of the Deluxe Set is referenced as DTCL-8-2813 in the Goldmine Record Album Price Guide by Martin Popoff, 2009.
The "Set" is described as the Capitol Record Club edition, having a blue border on the box, with custom pressings of the LPs with DTCL prefixes.
Like you, TOKENHIPPIE, I have never seen this. Happy hunting.
There is a mono deluxe box set , however there is no such label# TCL 2813. it's all an illusion like what duophonic really is, not what capitol says it is. but i digress, the mono albums are the original T 2458. T 2354, T 2269 . THERE IS NO DESIGNATED TCL 2813 ON THE LABEL. However there is a 2813 on the back of the mono box set without the TCL. The only place you can find TCL 2813 is on the spine of the box set, which is the official title and label # for Capitol Records and it's a black spine different than the maroon coloured spine on the Duo.
There allegedly exists a Capitol Record club of the Deluxe Set with a blue spine.
Closest I came to seeing one was in a Denver record store in the late 70's. there was about 25 deluxe box sets all stacked up against the wall on the second floor above me where only the employees were allowed up there. I recall taking a long look at them and i thought i remember seeing one with a blue spine but it could've been a black one instead. regardless i never could investigate it , so it remains unsolved.
I do have a mono box set.
