The Machias Wild Blueberry Festival is an annual festival that celebrates the berry — a nutritional powerhouse — for which the Machias area of Downeast Maine is famous. This event cover from @McGeekiest Cachets features two wild blueberry plants framing "Wild Blueberry Festival" in a botanical font. Two 1999 "Blueberry" stamps (Scott #3294) are cancelled with a pictorial "Machias Wild Blueberry Festival Station" postmark (in blue ink) from Machias, Maine, 04654 dated August 20, 2016.
