Used Book in Good Condition
This is the correct answer. The photo appears in the book Propaganda and Dreams by Leah Bendavid-Val
This is wrong tho - there are unmasked persons in the photo, suggesting no presence of gas, they wear soviet style uniforms and pre-WWII soviet gas masks
Anyway, the photo is usually credited as Viktor Bulla - Pioneers in Defense Drill, Leningrad (1937) - which is much more plausible than the Japanese island in your link
Apparently the photo was lifted from this book
Also here is a good analysis of the details in the photo, translated by google from Russian.
