Unframed Frederick W. Bartlett lithograph edition 35/1000 Camelback O-4-O (Strasburg Railroad)

Each drawing began in rough pencil outline form and was finalized in free hand pen and ink; either as a series of dots (stipple technique), line drawing, or a combination of the two. The process was laborious, time consuming, demanding and required meticulous attention to detail for hours at a time. Original pen and ink drawing completion times varied from under one hundred hours to the extreme of over 800 hours. Following the completion of each original drawing, most were reproduced through a high quality offset lithography technique. https://www.fbartcreations.com/page/page/7999542.htm
