2020 Art Contest Winners


The 2021 theme of the MLGW Poster Art Contest is “Natural Gas Safety: Captain Mercaptan.” Memphis Light, Gas and Water wants students to help in designing the newest MLGW Power League Superhero, “Captain Mercaptan”:

The “Captain Mercaptan” mission is to encourage students to learn about gas natural safety and be conscious about Mercaptan, the substance added to natural gas to produce a smell similar to rotten eggs so that the presence of natural gas is easily recognized and avoided.

The “Captain Mercaptan” Poster Art Contest is designed to tap students’ imagination in creating a visual image of the “Captain Mercaptan” character while conveying knowledge that students and parents can use to be safe around natural gas. The students’ work should include their own original version of the “Captain Mercaptan” character.


General Rules:

  • The students’ artwork must include an original, graphical version of “Captain Mercaptan” character and a natural gas safety message.
