Canadian Pony Insulators -- One Collector's Research -- by Dudley Ellis, signed by the author -- great reference and in excellent condition. $20 plus actual postage - 4th class book rate should be less than $5 in the US.

NOTE: I'm selling these items 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.
