Re: media for oil prints

P.S., I did a quick search and found PY 74. It's an arylide, which
doesn't tell me much, because there are arylides and then there are
arylides-- PY 1 and PY3 are not very lightfast; PY 65 and PY 97 are
very lightfast. The fact that PY 74 isn't used in any artists paints
makes me wonder about its lightfastness. I'd recommend looking it up
through Color International; I can't right now because I have to go
finish clearing stuff out of the house I've just moved out of.
