Canadian Guide Dogs for the Blind is collecting used stamps. We have been asked to provide further information for our contributors about the stamps we collect. This protects the perforations. If these are damaged the stamp is worthless. There is no need to include the postmark.
Metered postage is of no value as there is no actual stamp.
This also applies to the printed stamp on air letters. We have had a great response to the stamp drive, keeping us really busy. Our thanks to all our contributors for their continuing support. Yours sincerely, Volunteer Stamp Collection Group For the Canadian Guide Dogs for the Blind. I know that there's a collection box for these stamps at the Willow Bluffs Area Guide Shoppe, as well as at the Guide House in Ottawa, Ontario.
