Today is National Arbor Day in the United States. National Arbor Day is the last Friday in April, but many states observe Arbor Day on different dates according to their best tree-planting times. Other countries that celebrate Arbor Day also do so on different dates.
The American Arbor Day originated in Nebraska in 1872. (Read about its history here). One of the traditional ways to celebrate Arbor Day is to plant a tree. This postcard is a "SEEDCARD" ©1966 with a packet of Genuine California Redwood Seeds. The card folds up for mailing. Inside the card there are planting instructions and information about redwoods.
