1897 OHMS Acknowledgement of Receipt for Registered Letter

1897 OHMS Acknowledgement of Receipt form for an inland Registered Letter, used from Lower Mount ST R.O. (Dublin) to Buttevant, Co. Cork, the stamps cancelled first in pencil, then tied by Registration Office cds's, the front of the form with an almost complete but slightly oxidized strike of the rare experimental "Dublin / Registered" rubber cds in purple (time in minutes), returned free to the Registrar of the Pharmaceutical Society of Ireland. A wonderful combination of Official Stationery and rare cancels, a positive enrichment for any Exhibition collection of this difficult collecting area.
