They took a long time to piece together, but at last the mosaic artworks for Palmers Green station are in place. They've been installed in existing recesses in the wall underneath the stairs to Platform 2 and can be viewed as an ensemble from the very front of Platform 1.
The mosaics were commissioned by the Palmers Green Action Team (PGAT) and created and installed by Alex McHallam and Tamara Froud. There are more photos on the PGAT Facebook page.
