Quite right about Aunt May Voss,...my bad.
In the original comic book (first issue), he could not climb without his suit. He designed it with the 'hooks' as it were.
He could scale objects well, but could not go past vertical to the upside down position without his suit.
His change to his web solution was in direct response to the city governments complaints about the webs hanging around on the buildings. In one of the panes, an engineer shows what the city would look like after years of spideys abuse.
Osborne wore a mask, but the rest of him was morphed from the person to the gobby look.
I would scan in the issues, but copyright infringement would bite me.
Yes, I have a first edition Spiderman and a first edition Superman. Both in mint condition.
