My 2 cents, but this will probably cost you a lot more. Find a shop that will scan your artwork, clean up the staple holes (simple photo-shopping) and then print to a nice firm surface in the size you want. Then frame and hang the result.
And for researching issues of Mainline Modeler, one of the historical societies (I think it's the C&O) sells a DVD (it might be more than one) with all issues that can easily be searched. Then, donate the mags to either a forum member, a library, an LHS, or some local kid who might make better use of them.
