Help identifying artwork/value

[daugher4]

My father has had this artwork for a few years and is convinced it is worth something. We haven't been able to find any information on it, but it does look like an original artwork. The artist signature is hard to make out, but the best we can read it is Mark Dwayne Goodman. Several family members have said it looks like it could be The Doors or Led Zeppelin. Any ideas?

Can we get a good close up of the signature ??

Actually it looks like Mark Wayne something....

Bigwull and Ghopper may know the group,, if that's what it is,, they are the members into that music !! I found a Mark Goodman and a Mark Duane Goodwin !! Mark Goodman did portraits of some pop groups but saw nothing like this !! Its possible that this was a preliminary sketch and the portrait was not done for some reason !!

I looked up Mark Goodman and although it was a promising lead, the signatures don't look at all alike.

I'm also thinking the first letter of the last name could be an S.
