I will post the whole booklet online when I can get a date estimate. I always try to include dates in the file names if I can. It is not easy to change the file names once uploaded to the Internet Archive. If no date estimate, then will upload without date.

I'd expect around 1935. There's no lead to be found online about the title?
There's a wikipedia about the carbro process that mentions this company; maybe that's a start?

"In 1919 bought the right to the Carbro process (carbon prints made from bromide prints), which became popular in the 1920/30s."

These might not be very useful for your purposes, but gives a rough idea of the time period.
