Since almost 2 years nobody posted anything regarding those 2 new tiles and the trail went cold, I decided to try something crazy, it seems.
I already have the first 2 and they are originals, with "K" on the back. Since my group don't play with 'le sac' we can't use those with "K" on the back. I saw someone from Spain that printed all of them on the blank ones that Cundco offers and they are with "C" on the back.
I am offering those 2 originals (Hero at the Crossroads & Baba Yaga) for all 4 of the russian promos printed on tiles with "C" on the back.
If somebody is printing those and can make a good job, I even can supply him/her with any resolution scans of the first 2 tiles.
