When I read this I remember the lyrics of the Grateful Dead's "Foolish heart"
"Shun a friend
Shun a brother and a friend
Never look
Never look around the bend
Or check a weatherchart
Sign the Mona Lisa
With a spraycan, call it art
But never give your love, my friend
Unto a foolish heart"
Giving a priceless painting to a furnisher refinisher is just foolish. Hell I am a journeyman level furnisher finisher and would never accept a job like that.
