Kupferstich/copper engraving??

This picture doesn't look like a copper engraving to me, because of the grey scales. But maybe its a colourized copper engraving (published in black and white and scanned from a book)? If the quality had been better it would have been easier to decide. 92.32.219.46 13:09, 10 June 2013 (UTC)
