Can't find the right bag size for old Disney magazines 0

[Sayntin]

I have some Mickey Mouse Magazine comics from 1938, problem is I can't find a bag size that fits them.  GA is to small by width, magazine size works for width, but not the length.  I bought some life magazine bags and boards, but those are waaay too big.  I don't know where to go to get the size I need.  13¼ x 10¼  for reference.

Recommend you try original art or portfolio size about 17 inch x 11 inch wide polybags. Not sure if they make mylites that size.
