This Canadian postal stationery envelope features the 14¢ definitive "Maple Leaf in Lines" design from the 1970s series, printed in magenta and blue. The imprinted stamp shows a modernist pattern of interlocking lines, symbolizing progress and communication. The envelope is additionally overprinted “17 NEW VALUE / NOUVELLE VALEUR” in both English and French, marking its revaluation for the revised postal rate.

The reverse side carries a bilingual message encouraging the use of postal codes: “Code it…Post it!” / “Codez et postez!”, part of Canada Post’s national campaign for better mail service. These envelopes represent a transitional era in Canadian postal history when inflation and rate changes required frequent surcharges and revaluations.
