Famous "FACTS NOT OPINIONS" motto at the Kirkaldy Testing Works - now Kirkaldy Testing Museum - at 99 Southwark, London south and a bit east of the Blackfriars Bridge (334 yards from the Blackfriars metro if you can believe everything you read on the internet). Note that I've severely cropped and lightened and otherwise edited the photo from Flickr.If this gives me any copyright rights, I declare those to be in the public domain, but of course Larrs Plougmann must still be attributed according to the license.
