I think this is the same as the Crescent brand hot pressed #202 illustration board. There was a artist supply store in Rosenheimer Platz also that had it but that was a long time ago that I was there. Hoped this helped.
I am not sure if this is an appropriate thing but I will admit that I use the blue painters tape on the back of my leather and then glue it down. Then the glue comes off when I pull the tape off the leather. Don't use the regular masking tape though ( I learned! ) it doesn't come free as well as the blue stuff.
