A secret art sale saw 143 artists exhibit their work in efforts to raise money for the Heath Robinson Museum.

The museum in Pinner Memorial Park has only recently opened to the public, and is dedicated to English artist Heath Robinson.

The Upstairs gallery at the museum displayed more than 170 canvasses works by anonymous artists from November 5-6.

Each canvass was on sale for £40 starting price, and almost £5,000 was raised over the weekend.

Ann Kopka, curator of the sale, said “This Secret Art Sale has unique characteristics; it is the only one we know of where artists who have agreed to participate are sent the canvases and where all the works exhibited are of a consistent size.

"It means that as a show it is stunningly effective and easier to appreciate the diversity of the art in different mediums.

"The Sale also gives people the chance to buy pictures by well-known artists at a fraction of the normal price."

This year’s Curator’s Prize, donated by Ann Kopka, and was awarded to Shirley Batten-Smith for her bronze profile of William Heath Robinson.

Ms Kopka said: "This is an intelligent, inventive and ingenious use of material.

"It reminds me of a gold medal and seems particularly appropriate in this year, the launch of the new Heath Robinson Museum."

Councillor Jean Lammiman, a trustee of The West House and Heath Robinson Museum Trust, launched the sale with a speech congratulating the artists and the volunteers who were stewarding the event.

Cllr Lammiman also introduced the Mayor of Harrow, Councillor Rekha Shah, who thanked all the contributing artists.

Rawlinson Gold in Bridge Street will exhibit the remaining canvases on November 26 as part of the Pinner Pantomime Evening.
