I collected sketchcards for several years, and one of the characters I focused on was Firestar from the Marvel franchises. I loved the Spider-Man and His Amazing Friends cartoon from when I was a kid, and hey, who doesn't love a red-head. Anyway, below are scans of non-sports cards depicting Firestar. I don't have a reliable list since she often appears on team cards, so there are likely many I am missing. That said, I am simply putting them grouped together by year. I'm sure I will change this up over time, but it's what I have for now.
Marvel Gems (base) #3 (/225)
Marvel Gems (base) Ruby parallel #3 (/99)
Marvel Gems (base) Topaz parallel #3 (/10)
