This is amazing. We found them when clearing out our old factory that had once been an auto paint shop in Morningside. They have been created from the over-spray. 

We have enjoyed them in our offices for the last number of years but alas are shutting up shop and do not have a wall big enough at home. 

1800*750 could be hung either way. 

It is chip board so quite heavy - they were bolted to the wall! 

There are 3 pieces in total. 2 x this size and then one large one.
