Early American Wrought Iron by Albert H. Sonn: 3 Volumes in One
This is a wonderful old classic which had been out of print for years. It is a massive book of over 750 pages and 3000 drawings! It is actually three books in one, which explains its rather expensive price.
Blue Moon Press had so many requests for this that they decided to reprint it. It is a celebration of the Village Blacksmith. It was reprinted on much better paper taking into account how dirty blacksmith's hands can be. The cover can even be wiped.
It's a great resource for both blacksmiths and architects. A great way to show customers the various choices they have when selecting wrought iron hardware.
