I have four. Not sure why I was saving them, nostalgia maybe - no other value except to you. Can not locate the covers at the moment, but I have saved everything else, so they may still turn up. I will look some more.
I can send you 3, keeping one as a souvenir, with the caveat that you will not horde them. If someone, someday is looking again, you should pass them along.
PM me with your address and I will mail by slow boat. If you want them Priority 1, FedX Overnite, send me your billing #......
