I'm not sure at all, but I guess G & 1:
G looks like a monument and the years I can read are birth and death of Karl Benz, so I suppose it is a monument dedicated at him.
I remember that during the first journey that Berta, Benz's wife, did with a model Velo, she was forced to buy some petrol in a chemist's (in German Apoteke) to be able to reach her mother's home, perhaps in Karlsruhe.
Now, in Pleasuredome n.1 is possible to read Apoteke, so I've thought it could be a drawing actually of that Apoteke. Perhaps you'll think I'm really mad
