A dedication plaque is a commemorative plate that is displayed on the bridge of most Starfleet vessels.
The plaque commonly displays the name of the ship, as well as its class and shipyard of origin. Many more recent plaques also display the ship's official motto, plus a list of notable Starfleet officers involved in the assembly of the vessel.
I made this prop from a brass metal plate, a old wood door from a cupboard and a plate of acrylic glass for the cover.
The text is made on PC than printed on transparent film and glued on the metal plate.
