How do I date an old bird print?

Dating relies on paper characteristics, printing techniques like early engraving versus later lithography, and any associated publishing details or artist signatures. Frame styles and mounting materials also provide reliable chronological clues, as ebonised and maple frames shifted in popularity across the Georgian, Victorian, and Edwardian eras.

Are these prints hand-coloured?

Many 18th and 19th-century plates received careful applications of watercolour by hand after the initial impression was pulled from the plate. Close inspection under magnification reveals the subtle brushstrokes and variations in pigment density that distinguish manual tinting from mechanical colour printing.

How should I display framed prints?

Display these works away from direct sunlight to prevent the fading of delicate watercolours and tinted paper stocks over time. Maintaining stable indoor humidity levels also protects the wooden frames and keeps the paper from warping inside the glazed enclosure.

What is the difference between an engraving and a lithograph?

An engraving involves incising lines into a hard metal plate, resulting in crisp, linear definitions under magnification. Lithography uses a flat stone or metal surface treated to accept ink where desired, producing softer tonal gradations and smoother areas of colour.
