SG_Tess let us know about one other site reporting the receipt of a box and that has led to a couple of other sites being found as well as the BadAssDigest.com site reported previously.
WikiBruce.com
ComingSoon.net
MovieWeb.com
Also the AlcatrazLegends Twitter account is also starting to post pictures of the material.
The boxes that were sent out to the other sites contained the same information and objects apart from one thing.
These pictures were taken from the sites above and collated into these versions by me.



The main thing for me that stands out from the information on the back is the dates of each card.
1910 - From MovieWeb.com, BadAssDigest.com, Collider.Com, SlashFilm and Mustang Magazine
1936 - From AlcatrazLegends Twitter and WikiBruce.com
1957 - From ComingSoon.net and GeekTyrant (video)

It shows one scene from 1960 and one from today, actually 2008, which was when the card was published.
When all the other material was the same in the boxes, these postcards stick out and are asking to be investigated, or at the very least noting and remembering for future use.
So we now have these years to consider 1910, 1936, 1957, 1960, 2008 (plus 1963 and 2012 of course !)
As always your thoughts and theories are welcome in the comments section and if you know of any other people with different post cards then let us know.
