There's another "Thunderbirds" episode by Frank Bellamy on eBay this time with a "Buy it now" price of £6,500 (or make an offer!)
The seller (d.g100) describes the piece like this:

TV Century 21 Issue 72 June 1966 Thunderbirds
Frank Bellamy Original Art
Very sad to let this one go
Includes great images or Thunderbirds 1 2 and 4
Signed by Bellamy
Colours still good and has all the original writing.  Please note the Thunderbirds title is a copy
Approx 65cm X 41cm
Available with conservation framing inc. Museum glass for collection
Post sent unframed

He or she appears to live in the Loughborough area for anyone that fancies picking it up with the "conservation framing". However I have to disagree that the colours are "still good", they're not bad but are somewhat faded. Compare the colours here to the other piece being currently auctioned and you'll see the difference, and here's the comic (with the usual proviso that comparing a scan of a comic with the original isn't exact) to make a comparison.

Scan of the comic as published TV21 #72

 But having said all that I was shocked how much was paid for artwork that appeared to me to be more faded than this example and it is one of the rarer double-page spreads!

Here are the other photos the seller has provided just for the record.
