These two pictures are from Smith's Strangers Guide to Liverpool, 1843.
The first one (picture on the left) is of the old Birkenhead Ferry, which was on the edge of Tranmere Pool behind St Mary's Church and the Birkenhead Hotel. The hotel and ferry were opened in 1820 and the church in 1821.
But I'm not sure what the ferry is in the second picture. I think it may be Tranmere Ferry, which was opposite Birkenhead Ferry on the south side of Tranmere Pool. Can anyone help?
