Grimm's speciality was visually documenting historical relics in the kind of detail that might otherwise have gone unreported.
For example, the British Library credits him with documenting the only surviving scene of the coronation of Edward VI.
Another example of a unique artistic recording is the 1790 ink-wash drawing he produced of the chapel at Calcot Manor in Gloucestershire, long since ruined, and a drawing of Samuel Pegge's church which was later rebuilt after a fire.
He also made a number of drawings of the body of Little Saint Hugh of Lincoln when his coffin was opened.

The British Library possesses 2,662 drawings in twelve volumes by this artist, covering many of the counties of England and a further 886 watercolours, in seven volumes, dedicated to the county of Sussex.
