...to Aunt May, in ASM 31.
Let me be more specific. So, in ASM 31, it was revealed that Petey had donated blood to her aunt. Funnily enough, though...it had NEVER happened in any previous issue. I`d think. I haven`t read ish 20. Maybe it happened in that one. Which I really doubt. especially, `cause Stan Lee himself implies it on the same page. SO, my question is, has this transfusion been shown in any issue of Untold tales of Spider-man? Or any other story set in to Spideys early career?
