This painting shows an old man holding up a ten shilling note to the light in order to find the watermark. The title suggests he has found a counterfeit note. Spencelayh's meticulous technique owed much to his early training as a miniature painter. It earned him the nickname 'the Human Camera' amongst his contemporaries.
Spencelayh’s small–scale genre scenes were immensely popular in his lifetime, and he was supported by several influential collectors and patrons. They remain very popular today. These two works were generously bequeathed by Alice Creed who lived in Rochester and knew Spencelayh well.
