Clearly they are from the same place. But also, clearly a different day/shot. I think Earle Shettleworth at the Maine Historical Society(?) will be able to tell us more about this picture. If I am not mistaken, he has already identified it as one of a "Generic" clam bake where they put the name of the place: Squirrel, Peak's Island, anything; on the post card but keep the same picture. They also call it a Clam Bake. On Squirrel, we now have lobster bakes. but maybe that is more recent.

Above is an image from the great Maine Memory Network

You have to take a look at the 20 Squirrel pictures. Just search on the word Squirrel. They are mainly from the Stanley Museum of Stanley Steamer car fame. The Stanley family had a house on Squirrel.
