A rare and historically important cartoon engraving which lampoons the former Prince of Wales George IV is expected to be a major attraction when it goes on sale at The Chester Antiques Show at Chester Racecourse from October 12-15.

Antique dealer David Harvey of W.R.Harvey is offering the long engraving which measures six feet.

He explains: “This important satirical engraving that pokes fun at the Prince of Wales is one of only three known to exist, the other two residing in the British Museum and the Library of Congress, Washington, USA.”

Titled ‘The Prince’s Bow’ it shows 19 figures comically imitating the famous moment when the Prince took a flamboyant bow before the throne at Westminster Hall, an overly gracious gesture to the symbol that represented the authority of his father, King George.

This was at the commencement of the famous trial of Warren Hastings, former Governor of India, by Parliament, which lasted seven years and resulted in his acquittal.

The ‘Prince’s Bow’ moment was widely reported and the subject of considerable gossip and mirth.

The hand-coloured engraving was published in three sections by William Holland in London, March 17, 1788 and was taken from the original painting, now lost, by the artist F. G. Byron Esq, (1764-1792), a relative of Lord Byron, the famous poet.

It will be on sale for £7,000 and offers the chance for a collector to acquire an important piece of royal and political history.

The Chester Antiques Show also features fine English period furniture.

W.R. Harvey from Witney offer a range of Georgian and Regency formal pieces including dining tables, sets of chairs and library furniture; while more country oak and dressers are on offer from local dealer Mike Melody.

Also showing furniture is C.S.Moreton from Scotland, with a selection of very affordable and stylish Dutchpieces.

Altrincham dealers Church Street Antiques offer a broad range of lavish 19th & 20th century items and very decorative standard lamps and mirrors.
