I drive by this wall everyday at the Dunkin Donut shop. The stones are actually several different colors, but I'm trying to "see" in black and white this week.
Well STONE me, that looks like a chip of the old BLOCK. What, you go by the Dunkin Donut shop and not go in. Lovely capture in B & W but they seem to have missed the mortar. (Cement to the unlearned)
