This image shows the rock outcrop in the Lower Wisconsin Dells known as Pulpit Rock, with an adjacent formation called Baby Grand Piano.
There is no description on the back of the card.
The Pulpit Rock is so-called because it provides a convenient platform for people to stand on and overlook the lake. It is large enough to hold a half-dozen people at the same time. To the lower right, and leaning at an angle, is a darker formation which looks generally like a piano lying at an angle against one side, with the leg resting against Pulpit Rock.
This card likely dates from the 1940s.
