Eine E & S
In 2006 I went to an EINE exhibition held at the Electrik Sheep up in Newcastle.
At the same time Eine decorated shop front shutters in the city with his trademark alphabet letters.
I found: A C E F I J K L M P Q S.
Here are E and S.
These were the shutters of the Electrik Sheep on Pink Lane.
Update: July 2013 - no longer there. Neither is Electrik Sheep.
