Last Friday I got two postcards: one from Estonia and one from Croatia.
The card from Estonia shows an old map of the country.
With a nice stamp:
Posthorn (from set of three) (issued 18-01-2017)
Manilaiu Lighthouse (issued 07-06-2018)
with a special postmark of the EstEx Stamp Exhibition
100 years Estonian Stamps (issued 13-07-2018)
with First Day Special Postmark
Thank You very much Jaan!
