Bust: Rondel 4
Site: Four mystery rondels (4 memorials)
EC2, King Street, 28
These rondels, below the second floor windows, are numbered from the left. Under other windows are: "T. C. C.", "1868", "H.H.".
These look like portraits to us, especially number 4 with his moustache, but we need some help identifying them.
