Hidden In Plain Sight

In following up on the crane activities from yesterday, this morning I photographed a large yellow piece of machinery that looks a lot like Thomas the Tank Engine being hoisted up onto the roof of the Macy's building (see extra).  As I was doing so, I became aware of the fascinating window decorations in the background -- I'm not quite sure what they're celebrating, but there's a lobster claw and a scallop shell, and various nautical looking bits ... I think it's in the Primark shop, but I'm not sure.
