Hi Kim,
didn't know it existed, I have not seen the Michel 1920 listings, jut going on Richard C Witt's examples.
A cloudy memory suggests the reprints were a lot rougher in print appearance, but that needs confirmation.
A google search using epirus 1917 locates an old pic with a perforate surcharge
so it must exist, I cannot load that page, it just goes to an
ebay list.
Suddenly found my records, and I did know the perf existed , just forgotten

Linn's = "series was crudely reprinted"
