These  are both the same boat, but the one on the right is a much earlier
photo of it, probably taken circa 1924. It was built in 1924 at
Paducah and was steam powered. The Ash family sold their
rights to the ferry service in 1923, and so the new owners
(Judge C.W. Wilhoite, Carrollton) bought this boat from Paducah
and named it "Ohio". It burned in 1936, and was rebuilt with a
diesel-powered paddlewheel. So the photo/postcard on the
left is circa 1937.

When the Wilhoites decided to get out of the ferry business
(early 1940s?) the McKay family of Lamb took over the service
until it faded into obscurity by 1952.
