The one herewith was on one of my own paintings of 1980. The languages used on the label, are Afrikaans (my home language) and of course English.
The framing company E. Schweickerdt (Pty) Ltd started operating in 1902 and they closed down about a year and a half ago. The tree in their logo (with the letters ES) is after the style of one of South Africa’s most famous landscape painters JH Pierneef. As far as I know the first painting Pierneef sold, was sold to Emile Schweickerdt about the time the company started up.
