Does anyone have any info about this stamp?
Can it be pre 1940’s?

  1. I think it says “Valmistaja Taidepohja Pori, omistaja Y. W. Salko”, meaning “Manufacturer Art base (as in a canvas for paintings I think) Pori (a town), owner Y. W. Salko.”

    Quick google only tells that Y. W Salko bought some buildings in the 1960’s, so he might have been around owning a business in the 40’s too.
