I came across this Luxembourg SC#O86 with the unusual feature that the overprint appears on the back—something I haven't seen on any others in this series. What do you think about it?
Note that the overprint is reversed on the gum side. It is ink picked up from the previous sheet when the sheets are stacked atop one another. Sometimes referred to as "offset", sometimes called "setoff". A search for either term will turn up threads discussing this on other stamp issues
