thank you very much for the reply. I've already placed bids on several items in the auction.
I am a (fairly new) collector of so-called 'Tarnschriften' (camouflaged antifascist pamphlets) but am now extending my collection to include camouflaged ww2 leaflets. I've already got a few in my possession but would like to add to my collection if possible.
I have your seminal book on the subject to help me get to grips with the subject. In short, at the moment I am quite happy to buy anything that comes along which could be considered as 'camouflaged'.
