Where was/is this?
There was a Robert JONES at 240 High Street....
http://historical-advertising-bangor-north-wales.2293025.n2.nabble.com/Robert-Jones-240-High-Street-td2302620.html.. but I'm not convinced, it doesn't look like a high street property. 240 today is the card factory
... but there are no points of reference. It looks more like Caernarfon Road...
