heroic_decepticon: before applying the stickers, may I suggest that you do hi-res scans of them and donate them to reprolabels? Maybe you can ask if they'd be willing to give you a set of those reprolabels at a discount price in return for your services.

That way you'd still be able to apply the stickers, and keep the originals unapplied too. Or if you really want to go ahead and apply the originals, at least reprolabels would have a set of them for other collectors.

Just a suggestion.
