So there's 3 bursts in those pictures: pickguard, no pickguard and bigsby. Which one of the 3 was the Beano LP? Or was it a different burst altogether?
It's quite possible that none of those are the Beano Les Paul, as it was stolen shortly after Cream formed. Most of those pictures are from late '66, so the Beano LP was likely long gone, and what you see are the various loaners that Eric used.
What a great shot:
I believe so. If I recall correctly, Summers mentioned in his book that he had a bit of a sideline gig selling "vintage" instruments of note. He knew early on that some vintages where worth seeking out.
