Vintage oil color paint

These are from the late 60s and 70s. This was from a old lady I work for and got it from her estate sales! These are unopen. They do not make these paint anymore from what I heard. One of the tube is a little hard. Not sure if it’s starting to dry out or not. It’s the one that I had pointed to in the picture. The rest are still squishy. OFFER ARE WLCOME!
