This is a preliminary drawing of the ECS Horizon, the cargo ship in the episode "Horizon" by Trek artist John Eaves. The drawing is version "A", which was not used as the final design of the ship. What I love about this drawing is John's drawing of the NX-01 Enterprise soaring above the Horizon. The drawing has a notation at the bottom that says "Approved - Dan Curry" which means that Dan Curry approved this as one of the designs under consideration for this cargo ship. The screencap shows the final design for this ship.
