These are not my own words so please forgive me for being idle with your request
Copperplate writing or Copperplate calligraphy, is a calligraphic style characterised by its graceful flowing and shaded strokes
Copperplate comes from its 18th-century origins when the scribes handwriting was transferred onto copper plates for engraving and printing
The technique involves creating thin upstrokes and thick down strokes by varying the pressure applied to the flexible pointed pen nib
