I have an old edition of Hugo Steinhaus's Mathematical Snapshots. The title page lists the publisher as G. E. Stechert & Co, New York, Leipzig, London, Paris. Then in lighter type (probably a rubber stamp), Philadelphia Book Company, 22 North Ninth Street, Philadelphia, Pa.
At the top of the following page there's a line that's been whited out, followed by PRINTED IN POLAND. Bottom of the page says PRINTED BY KSIAZNICA-ATLAS IN LWOW (with a few diacritical marks I won't try to reproduce).
I'd like to know the date of this publication - presumably that's what was whited out.
Answering myself so the question doesn't linger on the open queue.

I happened upon this question/answer while looking up additional bibliographic information about the Steinhaus book. Googling “Kalejdoskop matematyczny” gives the Wikipedia page Kalejdoskop matematyczny, which says that in 1938 there was a simultaneous publication of the first Polish edition by Książnica-Atlas (Lviv, Poland) and the first English edition by G. E. Stechert and Company. Later printings and/or editions in Polish were published in 1954, 1956, 1989.
What follows is information I’ve previously had in my personal records. Later editions in English are: 2nd edition by Oxford University Press in 1950 (vi + 266 pages & MR 12,44e & Zbl 41.27502; reprinted by Oxford University Press in 1960 – MR 22 #5541), 3rd edition by Oxford University Press in 1969 (vii + 311 pages & Zbl 169.29003; reprinted by Oxford University Press in 1983 – Zbl 513.00002, and by Dover Publications in 1999 – MR 2000h:00002 & Zbl 955.00005).
