Mystery postcard-Germany

Another mystery postcard arrive (or my brain is just filled with so much info. :D) yesterday July 25, 2017.
This is my 2nd meetup card and came from Germany. In case you don't know, my first-ever official postcard in Postcrossing is a meetup postcard and also came from Germany!
However, I forgot the circumstance why it was sent to me. Hoping that the sender will message me, please?

This is a meetup postcard took place in Erfurt, Germany on July 15, 2017. Thank you very much for this beautiful postcard! Look at the cute panda sticker and stamp, I love it!

Mystery Postcard - France

This is one of the postcards that I received last July 20, 2017 and another mystery postcard. May be the sender forgot to include the ID Number? or just another gracious person. Whoever it is, I would like to thanked the person who came all the way from Dijon France. :) 

I like the postcard showing the churches in Bourgogne or Burgundy. 

According to Google, Dijon is the capital city of the historical Burgundy region in eastern France, one of the country’s principal wine-producing areas. It’s known for its vineyard tours, autumn gastronomic fair and building styles ranging from Gothic to art deco.

This is my first ever postcard from France and I like their postage stamps. 

Mystery Postcard - Croatia

This is among the 7 postcards that arrive yesterday, July 20, 2017. Why a mystery? Since I forgot  who sent this or whether this is a result of swap and where it came from. Luckily, Google provided that Brijuni are a group of fourteen small islands in the Croatian part of the northern Adriatic Sea. 

The message is inspiring, it says: "Dream what you want to dream, go where you want to go, be what you want to be. Because you have only one life and one chance to do all the things you want to do"
Thank you for this inspiring message Ma'am Jasmina! I love the psotcard and the message!
The stamps features a somekind of a pattern on a clothe.

Hoping the the person will message me. :)
