This image shows a Michigan black bear in the wild near the lake with a similar name: Bear Lake, located in Kalkaska County, Michigan.
The description on the back states:
JUST BARELY AWAKE
Crashing through the grass and brush, this big guy looks like he might make it tough for somebody.
–Such bears are still present in various less urbanized areas of Michigan, but a far less common than during the time of this photo. This postcard was dated by the publisher, and is from 1951.
