I could only imagine another publication I may find that name:
The "75 Lat PWPW" or 75 years of the Polish State Printers - 1919-1994!

In 1929, they had 9 typography presses "Miehle", 1 monocolour offset-litho press, 2 bi-colour Voirin presses in the banknote dept. And also in other depts. they had 2 die stamp presses, 4 flat-bed "Sturmvogel" of Koenig-Bauer, 2 monocolour and 1 bi-colour Miehle press, but also a 4-colour "Iris" machine, later re-built into an "Orlow" type press!
That latter fact probably referring to what we now know better as the "Giori-process"!
