Why, that I believe is the flip-grid communicator that John Eaves designed for "Star Trek Generations."
It seems (as Eaves admits in "Star Trek Sketchbook: The Movies"), when the artist was called in to work on the first TNG-era movie, one of his first assignments was to design a "new communicator". So he sketched out a Kirk-style black and gold flipgrid model.
That's right, while Eaves had in fact seen TOS, he had never watched an episode of Next Generation. So he did not know that the delta-shield badges on the uniforms were used as communicators.
Yes, as incredible as it seems... and you have John Eaves to thank for the design of the Enterprise-E. :unsure
