EXTREMELY FINE. THIS IS THE ONLY RECORDED EXAMPLE OF THE NEGATIVE OVAL HANDSTAMP USED BY POMEROY & COMPANY.
This negative oval and the illustrated locomotive oval are the two rarest types of Pomeroy markings. The David Snow census in the Independent Mails book records just one of this type. It was used by Pomeroy & Co., prior to the Independent Mail period.
