Wanted - Cover With Atten Mills, Ontario Cancellatiion

A friend of a friend just moved into the original Atten Mills, Ontario, Canada, post office building, which is now a house.

He wants to find/locate/purchase an envelope/cover with a clear "ATTEN MILLS" cancellation. Apparently he found one on ebay for $400.00, but this is way out of his price range. He is not a stamp or postal stationary collector and simply wants to honour his home with a framed envelope/cover to hang on the wall.

I've agreed to search for one and will act as his intermediary.

If anyone has one they can part with, please email me through this forum.

You may be able to find obsolete cancelling hammers and other such devices - they are available for a lot of Ontario locations.

Thanks "CanadaStamp" for the suggestion, which I have passed on to the homeowner.

My special thanks to "jogil" who emailed me a link to a "Anten Mills" cover, which I have ordered and have accomplished my goal.
