Neither of these PHQ stamp cards are in my possession because I've sent them to people who collect mushroom cards. Personally, although I find them interesting, I don't think they are attractive at all and even verge on being sinister. Day of the Triffids and all that. I think I read that book too young.
The first, as you can see, was issued in 1988 and ten years later came the second. Interestingly, the 34p stamp was the highest value of the set, as was the 63p in 1998. Now 63p is the first class internal mail rate, just seven years later again.
