Gaby's drawing of a Vulcan
Vulcan was the title of a piece of art depicting such a titular individual.
In 2151, the crew of Enterprise NX-01 received several letters and drawings from Miss Malvin's fourth grade class at the Worley Elementary School in Kenmare, County Kerry, Ireland on Earth.
Among the drawings received was one of a Vulcan, drawn by a child named Gaby, depicting a person with green skin, exaggerated ears and an IDIC pin, standing against the backdrop of a planet and stars. The drawing also depicted two women, and a cat in an environmental suit. (ENT: "Breaking the Ice")
