X user @StuartY attended the Star Trek: Las Vegas convention in August of 2024. Among the great cosplayers present was this gem of a lady who portrays a Star Trek version of Lucille Ball.
For those not in the know: without the consistent and direct work of Lucille Ball, there would be no Star Trek. Therefore we Trekkies have nothing but reverence and respect for her.
The red-coiffed Lucy bears the Starfleet logo on her chest, modified with a heart. I'm not sure what her cart represents. It might be a reference to an I Love Lucy scene in which she fended off an aggressive vacuum cleaner salesman.
