Box Art Artist - RIP Greg Martin

Internet can be a mean place, but also can bring you a lot of information. We, along the life, receive information as many types: music, pictures, texts, everything wrapped up. But sometimes, the credits of who have done such things passes by, sadly, unnoticed.

There is a thread on NintendoAge forum which RIPs Greg Martin. I've never heard of. I made a lil and fast research and I don't find anything else citing this name besides these "RIP situation". Nor even crediting his works. Even a, faster, research on Moby Games I could not find this guy. The only font is this forum. This is the first time I heard of the guy, an he is dead! :/

He passed away January 3rd.

I have some of his works on my shelf right now.
This is a piece of the original post:

Greg started his career at Hanna Barbera. He worked on projects relating to the Flintstones, Jetsons, Yogi Bear and the rest of the Hanna Barbera line up. It was no surprise then that he illustrated the packaging for the video games related to these properties later on – he already had perfected illustrating these characters. Greg told me it used to come in handy at the bars too – as, in exchange for free drinks, he sometimes had Fred and Wilma doing… things... on the back of cocktail napkins that NEVER made it onto the product illustrations 

So, believing the information of these moderator of the NintendoAge forum, this post is to honor Greg Martin works. RIP dude.

there is a lot more of his works on the [link]

this is meant to be his [official site]

To find it, I used this "sonic greg martin -comic -issue -passed -rip -passes -dies -morre -fallece -morreu" on google. Pretty underground, uh? I don't find any reference on the History of Sonic book yet.  His name is also credited [here]. But I don't know since when this exists.
