Steel engraving is a means of printing by etching and engraving on a steel plate. Introduced in the late 1700s, it was used for book illustrations and banknotes. Examine US paper currency and you’ll see fine illustrations of this art. These two small portraits–of King Edward IV and King Henry VII–are very early examples of steel engraving. The portraits and their frames are estimated to be about 200 years old. Because these engravings are protected within their glass frames, it is impossible to see, in these scans, the clarity of the printing and the near-photographic detail captured by the unknown artist. If you would like to visit our royal guests, you’ll find them for sale in the jewelry display case.
