Selma is the owner of a comic book store in Coolsville.
Physical appearance[]
Selma is an African-American female with a perfectly-shaped figure, and black, curly hair with a red ribbon tied around it. She wears glasses with large, round lenses and without frames, yellow hooped earrings, a green jacket with a white shirt underneath, a blue skirt, red and white sneakers, and green socks.
Personality[]
She's fond of Shaggy Rogers as she knows him since he was very little. She sympathises with Mr. Cashmore's secret love of comics, because she reads them too.
History[]
Early life[]
Shaggy had been coming to her store since he was an infant.
A Pup Named Scooby-Doo[]
Season one[]
She held a booth, called Selma's Comic Classics, at the first Coolsville Comic Book Convention, and sold Shaggy one of the three remaining first issues of Commander Cool & Mellow Mutt. She had one copy left for herself, but it was stolen by Dr. Croaker, though she got it back when Croaker was caught. When the gang confronted Mr. Cashmore about him sneaking around with comics and sticking them in his car, he confesses that he actually loves comic books, but given that he's well into adulthood (he claimed to be 55-years-old), he felt too embarrassed to admit it. But Selma and the Scooby-gang sympathized with him, with Selma freely admitting that she herself still reads comic books despite being an adult (although this seems to be a given, since she does run a comic book store for a living).
