Along with N.R. Woodward's books this was the first book to introduce CD numbers. This is a signed version in great shape. Millholland's Bicentennial Edition - Most about Glass Insulators -- 1976 -- figure $15 plus actual postage (can use media rate which is very reasonable).

NOTE: I'm selling these insulators on behalf of the Jim Fielding estate -- PayPal (no fee friends and family) or checks are both accepted - I'll provide instructions. I'll also be handling all the packing and mailing.
