Of course I had to find out more about that Indy drawing. You can buy this at the Indy store of course and they have this to say:
Acme Archives has pursued some stellar talent to bring Indy fans a new series of limited edition fine art lithographs, including this fun animated take of a classic Indy scene by artist Patrick Schoenmaker. This 13"x19" fine art giclee on paper, limited to just 245 pieces, depicts the tooned-up Indy and Marion staving off the darkness in Raiders of the Lost Ark's Well of Souls. This piece makes you wish we could see a fully-animated Indy adventure! Each print is hand numbered and comes with a Certificate of Authenticity. About the Artist Currently living in Utrecht, the Netherlands, Schoenmaker is studying animation and has drawn several comics appearing in such magazines as Break Out! and Stripnieuws.
One of the best sites for Indy news is theraider.net, which has more artwork and links to his blog and portfolio site. Here a sample of his work:
