One of the 6 sought after TV 21 Extras (or Summer Specials). Genuinely scarce. Turns up on eBay UK once in a seldom while. The free gift of WASP and Stingray Badges, add about £100-125 to the value. I have seen only two examples of this badge in my time.
This was the first of the TV 21 Specials. It was advertised for the first time in TV Century 21 #17 dated 15th May 1965.
In Jul 2010 a Near Fine example sold on eBay UK for £69.
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
