I found these postcards in a dime bin at the Book Eddy. They aren't great, but too good to be lost to an album in someone's basement.
The first two celebrate the Lobster Festival in Rockland, Maine. The first card doesn't have a date, but the second card talks about the Maine Seafoods Festival in 1955, also in Rockland.
There's a nice little story from the Bangor Daily Press about this year's festival, which took place last week. More info can be found at MaineLobsterFestival.com.
Hazel Park, Michigan, sits in the heart of the southeast corner of the state. On May 29, 1966 they had a parade celebrating Memorial Day. The top card is the Hazel Park Jr. High School Band.
The Jr. High card says that this photo was taken at John R & 9 Mile Road.
The Hazel Park Sr. High School Band...
I don't know if the city still has a parade or if the schools participate in it. I'll contact them and see if they do.
For more postcards, take a look at my A Century of Ballparks post.
