Three postcards of the Margate Harbour area from the air, the top postcard is pre 1924 dated by the two lifeboat houses on the Jetty. The second postcard shows the Fort Hill dual carriage way development post (1938) which was completed post war.The Droit House looks like the post war replacement and the absence of the Camera Obscura bombed 1941 along with other buildings on the Jetty entrance indicates that this postcard is definately post war plus even though Margate College is visable on the present day Somerfeild site and Holy Trinity church is still visable yet both buildings were bombed during the second world war and were later demolished. So I reckon I could say about 1947 any ideas.
The bottom postcard is from my saved from the bonfire collection with the pre 1953 lighthouse. In this one the Tivoli goods yard can be clearly seen in the foreground.
