National Postcard Week is an annual event to promote the use of postcards, held in the first full week of May since 1984.[1][2] Started in the US, it is also celebrated by deltiologists in other countries.[3] Special commemorative postcards have been printed for Postcard week by various organizations, especially postcard clubs,[4][5] since as early as 1985.[6] As of January 2021, there is a savings of 18 cents to send a postcard versus a letter (40 cents versus 58 cents). During the Golden Age of postcards (early 20th century), the cost to send a postcard was half that of a letter (1 cent versus 2 cents). Pennies mattered at that time. For example, a loaf of bread might cost 5 cents circa 1915. In the age of text messages and social media, there are hints of a resurgence of interest in written communiques among younger people. There is a certain focus required to write a postcard, and that focus results in a beautiful display of care for the recipient. Vintage postcards brim with symbology and art history.
