How about commissioning a custom comic book art piece for her? You can reach out to some independent artists who specialize in the field and have them create a unique artwork for your girlfriend based on her favorite comic book character or scene. Additionally, you could also put together a gift basket of her favorite comic books or graphic novels, along with some fun comic book themed merchandise such as t-shirts or toys. Another option could be to buy tickets to a comic book convention or festival, which would give her the opportunity to explore new comics and meet some of her favorite artists in person.
Or you can get her a star map with the date when she was born.
