1869 folded letter from Reutlingen (postmark Reutlichen July 30, 1869 to Zürich (Switzerland). Transit postmark of the Royal Württemberg railway post and arrival postmark on reverse.

Multiple Franking (MEF): The letter is franked with a total of 7 Kreuzer, green with rouletted edges, which was the correct international rate from Württemberg to Switzerland at that time. 

The most remarkable feature is the horizontal strip of five across the top, complemented by a vertical pair on the right.
In "German States" philately, larger units like a strip of five on a complete letter are significantly rarer and more sought after than single stamps or pairs.
