I have a siddur printed by Romm Publishing from 1946 in New York. It is a copy edition of the siddur Seder Avodah that the Romm family printed. The oddity is that it has the prayer for the welfar of the Tzar and Tzarina Nikolai Alexandrivich.The printing date is well after the Communust Revolution and after all was printed or published in the USA!.It is an excellent pocket size edition with precise Hebrew text, I don’t kow to what extent the Romm family continued publishing books on the USA or if they had any connection to HBC.Anybody know?
