Hi Scott.
For sure, I never had seen that before too neither any comment about that.
Yes, I find that magazine cover in the net
However, I don't know were come from!!! US, Canada, Australia
I suppose the price are in US dollars!
I try search by name of supposed post man Heman Lee and goes to AeroManiacs web page.
May be Heman Lee can give us some information!
If you have any other information, please, post here
Thanks
José
