At one time, or so it seemed to me, dinosaurs were a very popular choice on Postcrossing wishlists. It was probably about the time of Jurassic Park. I bought this set of Royal Mail stamp cards and a second set which was issued more recently.
Of course, dinosaurs have now gone out of fashion and I have only managed to send out 4-5 altogether.
This is a post for Sunday Stamps, in its current home at "See it on a Postcard!"
