There are probably far more steel engravings and wood block prints that have been removed from books then those still in books. Its hard to go into a real antique shop (as opposed to flea market shops calling themselves antique shops) and not find them for sale. It is shameful when they have been removed from good books. About 20 or so years ago I knew a collector that had several thousand steels. I've lost track of him and he's probably passed on by now. I wonder want happened to his collection?
