One of a series of cartoons on the disputes between the Church of Scotland and the government, attributed to the Edinburgh artist and caricaturist Benjamin Crombie. The title refers to Joseph Mainzer's (1801-1851) famous singing manual of 1841; in the present lithograph Mainzer attempts to get the members of Assembly to sing in harmony.
Uncoloured lithograph cartoon (58 x 41 cm).
In very good condition, with a number of marginal comments written in pencil in a contemporary hand along the lower margin, beneath the caption text.
