Hulk and Thing Sketch Cards

My sketch card collection tends to be pretty focused on a couple of characters, but I have to switch it up from time to time when something jumps out at me. That was the case with these sketches that I purchased from an eBay seller a while ago.

Based on the 'Fantastic Four' logo, I thought these might be from one of the Marvel trading card sets put out by Rittenhouse, but when they arrived I found that this was just a logo and some design printed on relatively thin personal stock. I probably could have figured that out if I'd done any research, as the cards from the Rittenhouse product were in the vertical format and had the word 'Archives' printed after the Fantastic Four title. Anyway, I don't have much information on these sketches, not even an artist's name. It looks like the artist's initials are 'LS' and the sketches are dated '08.'

This first sketch features a close-up of the Hulk's face, and he is looking might angry. I really like this sketch, and I wish I knew who the artist was.

The second sketch features the Fantastic Four's ever-lovin' blue-eyed Thing, again from an up-close perspective. It appears that he is about to announce that it's clobberin' time.

These sketches feature the characters that two of my sons are named after. If I knew who the artist was, I'd consider trying to commission sketches of my other two boys, although in my recollection Nightcrawler doesn't have much connection to the Fantastic Four. Thing is an original member of the team, while Hulk and Wolverine were members of The New Fantastic Four in the early 90's. Hulk and Thing also have a long-standing rivalry, as Thing is one of the few heroes who can go toe-to-toe with Hulk when he is rampaging uncontrollably.
