ToynbeeTile - Fake :(
I thought I found Los Angeles' first Toynbee Tile just outside the crosswalk on the corner of W 6th and S. Olive by Pershing Square. But the the Toynbee folk got back to me saying this is a copy cat House of Hades fake. I googled HoH and found they've made many tiles similar to this.
Anyway, I visited the location of this HoH tile a few weeks ago and found it's been replaced with a newer copy. Photograph can be found in below link.
Here's another House of Hades copycat tile I found, also in Downtown Los Angeles.
Two more fake Toynbee Tiles. Found April, 11th 2014.
