There are 3 new promos cards that have been inserted into the 2013 Mystery Boxes.

Memoirs of Sherlock Holmes Mini Magno 1,
Beyond Stocker's Dracula Unnumbered with Green back limited to 500,
Contemporary Erotica P3 Promo Card from Cult Adult.

I was unaware of the Sherlock, but some people found the latter 2 at the UK Memorabilia show last fall (including me)

BTW, on the 2 new Dracula promos (unnumbered and P2) and the 2 Cult Stuff Adult promos, EACH come in glossy and flat fronts, from what I am told. I can confirm that on the Draculas, as I personally have two versions of each

Thus, there are 2 versions of all 4 promos
