The Gates of Heaven

This time not some document or photographbut a little printed book. It is 8x5cm sized and 3cm thick.

As I do not read yiddish, I posted this picture on Facebook yiddish page and asked what one could make out of it.

The picture got many comments. I add them here ;

It's a siddur - book of prayers.
Printed in Warshaw by Aaron Tsaylingold. Naleski (street) 32. This street was in center of the Warshaw ghetto. The book would be part of 'Sfard' hassidim religious current (not to be mixed up with sefarad), google 'mussakh sfard' to know more.
The book title is "The Gates of Heaven - book of prayers for the whole year with letters bigger than in other siddur and with punctuation"
