On my Google travels yesterday, I came across this rare pair of 18th century German pictorial surgeon's cloak buttons, which are going under the hammer at Bonhams on 9th Nov 2011. Not only is the estimate value enough to make you raise your eyebrows (£700-£900), but so is the subject matter!
The first button shows a scene of a doctor administering an enema to a patient in a bedroom interior, with a sleigh bed & chamber pot in view, the second shows a patient using chamber pot with the doctor standing over him with the enema under the bed drapes! Each of the buttons are hollow nickel metal with rolled stud construction to verso and are 1.1/8in (2.8cm) diameter.
It's such a bizarre image to portray on Buttons, I wonder what the Surgeon, who wore these on his coat, was like? He must have liked to raise an eyebrow or 2!
