I certainly know Ray had a set of gloves that appeared through out RGB, not sure about the others…

Except in The New Jersey Parallelogram where they all wore gloves!

originaly slimer was gonna be a bad ghost

no those are real sketches i talked to the original owner of them and he obtained them from someone who worked on the show! Also that other auction was a cel used in the pilot episode that was discussed here on this site eariler most likely very valuable(yes back when slimer was going to originally be a bad ghost)
thanks

if it was from the pilot, i belive they would have all been wearing tan flightsuits.
