The Up Yourself Book by National Lampoon Magazine (Paperback, 1977).

Good-to-great condition, depending on your definition.  It has some general wear and the pages are yellowing from age, but nothing is torn or missing and I didn't see any notable damage.  Please see photos for a better indication of the condition.

Although this is a book and not a magazine, I will ship it in a plastic sleeve protector with a cardboard backer as I do with magazines.  The binding seems sturdy enough, but given the age, I don't think it would hurt to give it some extra support.
