I was given this artwork from a friend. He didn’t know much about it but I was able to find it’s artwork from Ernie Chen. #206 savage sword of Conan. I’m looking for more information like did he do the entire comic or only that specific page in the book. Also I did find a few on eBay for sale but if someone know the actual selling price it would be good. 

Any other information would be great.

I was given a hand drawn comic sketch from Ernie Chan dated 1995 and it’s titled savage sword of Conan. I am wondering if it’s rare and any other information about it any information you have would be helpful.
