Now THAT I like. Great printed cancel and on a 5c Proprietary to boot.
I agree with Bart on two points, that preprint paper folds are not damaged items like freak perfs are, and that Kelleher's openings and estimates on those preprint paper folds are WAY out of whack. Moreover, those Kelleher listings are retreads; they've tried selling them in 3-4 different auctions now with no takers at those prices. I doubt it is consigned material, rather they are buried in them.
There are people that collect preprint paper folds, but it is a VERY narrow market. I stay away entirely, unless there are other aspects of interest (cancel, plate variety, etc.). I've got a few that I have picked up along the way, but I've never paid a premium for them...
