Take a look at the many basic informations that can be found there that will answer most of your questions! A lot of knowing members invested their time to provide an overview.
Compare the marks you will find there and the marks on your "treasures"...

A reputable art dealer is seldom tricked - if he is reputable! Believe only what you see and what you know!
By the way: your posts creates no harm for me - only a sort of compassion and incomprehension....
