At first, I found it hard to believe that Benjamin Moore made artists' paint, but indeed they did. I found an ebay listing
(not the one that caught the original poster's attention) offering a Chrome Yellow and a black from Benjamin Moore. The tubes are pictured. If that's a real
Chrome Yellow, then the tube is probably quite elderly.
One of the first contributions to this forum I ever made concerned a line called Pictor, sold many a moon ago by Standard Brands. Pictor was made by a house paint manufacturer -- I forget which one -- and for that reason, most artists sneered at the stuff. But back in the day, we all had a couple of tubes of the stuff because it was just so
It wasn't bad. Wasn't particularly GOOD -- the thickness indicated heavy use of stearate -- but most tubes were useful. I still have some.
