A new acquisition for me is this Epirus imperforate oldy. However, per my relentless search, I cannot find it listed in Scott's Catalogue. I'm Hoping someone can assist with an alternate cat./#/valuation.
I have been unable to locate your example in any stamp catalogue. There are various bogus Epirus issues, probably from circa 1914. This looks to be based loosely on Greece SG190 but with the SG120/121 Victory statue by Paenius.
