I love this book. I have searched for this book for a very long time as there are no reprints of this book.
Willim Heacock was the expert during the 20th century on the PATTERNS in Early American Pattern Glass. Both sellers and collectors rely on the books written by William Heacock to identify Early American Pattern Glass (Pressed Glass) PATTERNS manufactured in the late 1800's and the early 1900's in the U. S. A.
I bought this book because I need to identify patterns in my own Early American Pattern Glass from the late 1800's.
