Wheatsheaf or lotus?

I’ve seen quite a few architectural representations of wheatsheaves – one of several symbols of co-operation – lately, mostly on Victorian and Edwardian co-op stores. So when I came across this version, on a 1935 co-op emporium in Long Eaton, Derbyshire (now functioning as a carpet warehouse, and still with a 1963 co-op open staircase inside), I thought it was simply an art deco wheatsheaf. But now I see similar items on other co-op stores referred to as a lotus, an iconic symbol used in art deco architecture. Seems to me it could be either; maybe the architect was keeping up with the times and art deco-ing the wheatsheaf, or perhaps indeed it is a lotus, and thus nothing to do with the co-op movement’s symbolism. Other examples welcome! And don’t forget to follow me on Twitter!
