White Label Promo 12 Record 73 Pop Group Conference Sampler Blue Mink Queen

For sale here is a WHITE LABEL record, Blue Mink, only when i laugh.

Released in 1973.
vinyl marked YAX 4644 and YAX 4643.
Vinyl looks in good condition, possibly never played, there is some dust inside the sleeve and 3 light scratches on the record.

Please see pictures.
This sleeve has collectability as it is the same sleeve as the first ever queen vinyl was supplied in.
Only 3 records were ever produced with this sleeve, they were all given away at this event.
I also have the very rare Queen vinyl from this event, with the correct sleeve, on auction in my other listings.
This is part of a collection that I am selling for a family member who inherited it from their uncle, who was an EMI records sales representative.

Please have look at my other listings, i will be listing them in the coming weeks.
Please note I am not an expert on grading vinyl, please forgive me if I have omitted anything obvious or important, if you need further details on anything please ask.
Thank you.
