I picked a Yugoslavia stamp too, but cannot say what it is about.I have 2 links this week - one to my wordpress blog - http://bit.ly/2UOTNHW and one to blogger http://bit.ly/2Skkqrz. Please tell me which you prefer - I may switch to wordpress in the future.
I like that simple but clever stamp.This is my link:https://mailadventures.blogspot.com/2019/02/sunday-stamps-y-for-yersin.html
I like those early Europa designs. I've not headed into the sun but the moon this week here
I had no idea that Yugoslavia was spelled with a J on their stamps.http://envelope100.blogspot.com/2019/02/y-is-for-year-of-boar.html
I have just learnt that this was a common design in a lot of countries!See, for instance, this list.
