Gray-McLean Co. Update

Two years ago I showed this sign from street level, both in 1996 and in 2007 photos. I recently got a chance to see it from one of the Block 90 Condominiums and was able to see much more detail. Turns out "Gray-McLean Co." is actually "Gray McLean & Percy."

I also discovered that the Gray McLean & Percy sign was painted over an even older sign:
MONOPOLE
CANNED
AND GLASS FOODS
