What I am looking for is info if I can make this picture as big as the one I currently have that came framed without making it blurry?

There is no negative.

Also, what is the best way to preserve this pic and should I do some high res scans as was suggested in the thread?

I know very little of this sort of thing so I don't want to go do something with it that I will regret. I also don't want to handle it anymore than I have to either.

Any info/suggestions about any of this would be appreciated.

Thanks.
