1984 (04) Urban Renewal - Cotswold RIBA, W1 Official - Doubled 2006 St Mary Axe Stamp

Unusual Cotswold RIBA, W1 Official.

But this has then been doubled with the 1st Class St Mary Axe Stamp from the 2006 Modern Architecture Issue... Quite a logical 'doubling' when you think about it !

Even the standard cover is Cat £45....

This is probably 'unique'....
