Is there any value in older travel docs and airline pamphlets? I'm cleaning out a persons stuff. Most docs are from the 1980 through the early 2000's. Includes things like TWA pamphlets from the 1980's, 1990's TWA boarding passes, and similar (and newer) stuff from United and Delta.

I'm inclined to just shred it all, but thought I'd post here to inquire. I'm often surprised by things people collect...
