I've sent request message to the team in e-mail ( info at torrorosso.com ) at 2013. 09. 14. and received these signed cards 2013. 10. 09.
Vergne's looking authentic by the clues.
I have an another Ricciardo signature (same card from the same address, requested at Daniel's official site) and it's slightly different, so I think it can be a real one too.
Any comments on authenticity are very welcomed!
