Wilkinson's Auctioneers, Doncaster, Yorkshire, UK. It is Lot 329 and is stitched with the alphabet and a series of ligatured print characters. The text reads: Honour thy father with thy whole heart, and forget not the sorrows of thy Mother, How canst thee Recompence them the things they have done for thee. It is signed Mary Conway Aged 11 years Ackworth November 2 1785 (?). In a modern glazed frame, it measures 10 ins x 12½ ins (25 cms x 32 cms). The estimates are: £100-£200. There is no mention of Mary Conway in the Ackworth School Register, so it is possible she attended a school in the village of Ackworth, or was a member of family associated with Ackworth School who adopted some characteristcs of the needlework practised at the school.
And while you are in Doncaster, don't forget a visit to the local chippy for your battered Cadbury's Creme Easter Egg. (I don't believe I am writing this at breakfast....!)
