Flag created by CincyFlags for the neighborhood. 
Its symbolism, according to CincyFlags in [1]:
"This illustrative crown is a reinterpretation of the old Queen City Tour signs. The shape of the crown roughly mirrors the silhouette of Cincinnati’s Union Terminal.
The jewel design is meant to highlight the seven hills of Cincinnati.

Purple and Gold are an allusion to the royal nature of the neighborhood’s name."
