Large Axl Rose Sketch Art work question

A few years back while in highschool I went to the flea market and walked around. I came across a guy who had this huge sketch like of Axl rose. It was like a copy of the original. I bought it for $5 and loved it. My freind (also GnR lover) wanted it so bad he offered me $25 then $40 for it and I told him no. About a year later I was hard up for cash so I decided to sell it on ebay (around 1998) and loa and behold it ended up selling for $200. I was happy but ever since I sold it I have REGRETTED it more and more and was looking to see if anyone has any information on it or a picture of it if they could pm me, I am hoping to one day find another one and any information would help.
