PHORPRES

I found this brick at the side of a footpath this afternoon and was intrigued by the lettering in the Frog. LBC = London Brick Company but the rest was a mystery. A quick Google later and all was revealed:

The early brick presses only applied two presses to the powdered clay in the brick moulds. The trade-name Phorpres came about because Fletton Bricks made in Bedfordshire are pressed twice in each direction so that they are literally 'four pressed' if the phrase is pronounced quickly it becomes Phorpres! The logo for Phorpres bricks can be seen here.
