So, I stumbled upon this website in search of some Journey Artptint and I found some pretty fantastic art print for sell and at a reasonable price if you ask me.
I don't think they are limited or oficial. Though, you can see 2/280 in the lower left corner of the journey artprint ( not sure if it was for the first 280 or not ), if thos artprint aren't official, I wonder how they are allowed to make art of games without copyright infringement. ( if someone have any information about it it would be great )
the art comes signed by the artist and with a seal of approval from the shop.
here are a few sample of some their art print.
