Mackintosh find at car boot sale

The drawings of Auchenbothie Lodge are expected to sell for up to £6,000

Rare Charles Rennie Mackintosh drawings bought at a car boot sale in Glasgow for £10 are expected to fetch up to £6,000 at auction.

The three drawings are of Auchenbothie Lodge in Kilmalcolm, Renfrewshire.

It was designed by Mackintosh about 1900 as a gatehouse for the mansion of mining engineer, HB Collins.

The auction at Bonhams in Edinburgh on 15 October will also feature a rare Mackintosh cabinet, which is expected to go for up to £100,000.

The vendor of the drawings found them in a bag of items bought from a car boot sale two years ago.

The pencil and colour wash drawings show the cube-shaped cottage with a high pitched roof and latticed windows.

Gordon McFarlane, a director at Bonhams in Scotland, said: "Mackintosh's architectural drawings appear very infrequently at auction, even less than his furniture designs.

The rare Mackintosh cabinet is expected to sell for up to £100,000

"Many of his surviving designs are in his estate collection which is now held by the Hunterian Art Gallery at the University of Glasgow.

"There are related studies for the same commission in the Hunterian collection."

Also included in next month's sale is a rare Mackintosh cabinet, which stands at three metres long and commands an estimate of £80,000 to £100,000.

Made sometime between 1894 and 1896, it is thought to be the first piece of Mackintosh furniture to have an inlaid pewter and ceramic floral motif.
