For Interest and reference, ive taken a couple of pics from my computer screen , from BBC iplayer of the Antiques Roadshow 18th March 2012, can't imagine there is any copyright problems with that ! ?
The link to the iplayer recording is,
http://www.bbc.co.uk/iplayer/episode/b01dy7s0/Antiques_Roadshow_Series_34_Yorkshire_Museum_1/Its about 20minutes in to the show.
A Sculpture of 12 bricks on a metal stand, No. 1 , dated 1971 signed Michael Harris Mdina Glass Malta ,
the chap asked for it to be signed when he bought it at the Mdina Studio in 1971.
Value given £1500-2000.
Maybe someone could put the clip on youtube ?? I'm not clever enough.
Heres a couple of screen shots, if i had been watching in HD i would have taken them from the TV ! I will look out for a repeat !
Hope its of interest,
Cheers
Andy
