This tube came to me by way of a retiring painter. The tube has seen better days and Bocour is no longer in business but the paint inside seems to be just fine. I appreciate that this Green Earth isn’t pumped up with phthalocyanine. It’s a weak tinter and not very attractive but in the right context, it can be just the color!
The brand link is an interview with Leonard Bocour at Smithsonian’s Archives of American Art. As a side note, Bocour made a line of mineral spirit soluble acrylics called Magna. Golden Acrylics has the formulas now.
