I recently came across an edition of the Noam Elimelech printed in New York in 1942 by Joshuah (Osias!) Wagschal. Interestingly it also contains letters of recommendation by the RAYATZ and Rav Herzog. Needless to say that later reprints of this specific edition ( I also have one from around 1980) have these letters deleted." - end of email.
The two letters both address him as הרה"צ, yet the emailer calls him Joshua (Osias!). Maybe that's what his stationery said? I'm kind of at a loss here. I should ask him, I know. Maybe he'll chime in in the comments. Is it the קארטשינער-פריסטיקער רבי? hard to tell. Let me see what we can learn from our readers.
