And the same person who brought these paintings brought today a silver-plated wine cooler from the last quarter of 19th century (incomplete) and I was browsing the hallmarks of this factory and the signature used on this cooler shouldn't be used on the silver-plated brass but on the silver-plated tin-based metals :P But the employee said that the cooler looks genuine to him and that wrong hallmark may be a mistake at the factory :P But this also may be a forgery that someone bought anonymous perhaps local perhaps foreign object and had it stamped with a good company name :P to get a better price :P
