How do I identify a true lithograph?

Examine the surface under a magnifying glass to check for the fine dot patterns of modern offset printing or the solid ink films characteristic of traditional stone lithography. Genuine nineteenth century examples show a flat ink layer without halftone screens. Look also for the subtle indentations left in the paper margins by the printing press stone. These physical impressions confirm the piece passed through a traditional flat bed press.

Are these prints hand coloured?

Many nineteenth century examples feature touches of watercolour applied by hand over a printed base. You can spot this by looking for slight brushstrokes and variations in pigment density. Pure chromolithography applies all colours through successive stone impressions, whereas hybrid pieces combine printed tones with manual pigment additions for extra vibrancy.

How should I frame and display them?

Keep prints away from direct sunlight to prevent the fugitive pigments and paper supports from fading. UV filtering glass offers essential protection for coloured works on paper. Maintain stable indoor humidity levels to stop the paper stock from cockling or developing foxing spots inside the frame. Acid free backing boards prevent chemical degradation over time.

What periods do these prints cover?

The selection spans from the Georgian era through Victorian production into Edwardian and mid twentieth century examples. Most material originates from the nineteenth century. Different decades favoured distinct subjects, from early sporting and natural history plates to later satirical cartoons and theatrical portraits.
