1968 Captain Scarlett Annual

I'd value opinions on a 1968 Captain Scarlett Annual, being sold to support St. Wilfrid’s Hospice in East Sussex.
The Annual is in good condition, and printed/bound by the renowned printers, Jarrold & Sons of Norwich…but entirely upside down!
The complete contents have been inserted in the hardback cover upside down and finished.
I’m assuming this production error is rare and somehow it passed “Quality Control” for dispatch?
Do you feel this might affect its value to Captain Scarlett/Gerry Anderson/Century 21 collectors?
Your thoughts would be appreciated…Thanks, Steve Mills
