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.
