L3-37, a key character in Solo: A Star Wars Story, was a custom-built astromech and piloting droid who was the co-pilot and companion of Lando Calrissian. She was a staunch advocate for droid rights, believing that droids were treated as slaves by their organic masters. Her body was a patchwork of parts from other droids, a physical manifestation of her independent and self-determined nature. L3-37's consciousness was eventually uploaded to the Millennium Falcon, making her a part of the iconic starship's very being. The stamp's design captures her unique, almost haphazard, construction and her confident posture, reflecting her revolutionary ideals.
