On Saturday I got two postcards: one from Belgium and one from Germany.
The card from Belgium shows Gaston. Gaston is a Belgian comic character created by André Franquin. He first appeared in the comic magazine Spirou in 1957 and is since then very popular in large parts of Europe. His adventures were translated in over a dozen languages.
With a matching stamp:
60 years Gaston (from set of five) (issued 28-01-2017)
with First Day Special Postmark
Thank You very much Gerda!
