There was a time back in the 1950s when you could still find Postes Relais cancels on postal cards in dealers' dollar cover boxes. Of course, a dollar still had some value way back then and most collectors were looking for stamps rather than covers.
Relais No. 11 (Walferdange) was one of my more common finds in those dollar boxes. But when I saw the Relais No. 11 cancel on the Bavarian postal card shown here (Michel P12(I)), it seemed unusual. Why? Well, I don't recall having seen it before as a receiving mark on incoming mail. But here it is announcing the arrival on September 25, 1886, of a 10 pf. postal card from Bavaria posted the previous day at Neustadt an der Aisch in what was then Bavaria, addressed to Dr. Muller-Weyman in Walferdingen b/Luxemburg.
With the World Wide Web at my fingertips, there's something new almost every day.
