Featured Any Info on Unsigned Painting? 1st Thought Mick Jagger (Stop Laughing!)

I found this at a new thrift store yesterday. At first I thought it was of a early Mick Jagger (stop laughing - my girlfriend was rolling on floor (but she forgot to get mad that I brought another painting home!) when I said that)!
It's unsigned, but the style/multi colors seem familiar - any ideas on artist by style/without signature?
It's also large - it's painted on the wood backing of what was probably a bedroom's dresser mirror (43" x 29")
I appreciate any help/thoughts - I know this one is probably going to stay a mystery!

 

Could you please look closely at bottom of right lapel to see if there is any writing. It could just be me but it also looks like letters on far right side like MW or something like that. Like I said it could just be me.

 

i like it, i get the feeling a self portrait of the person who looked in the mirror

and laughing as well, only cause you said don't laugh !

 

I see I th too

 

Here is bottom of right lapel - is this the area you were talking about?

 

Sorry, the other side

 

No problem:

 

I see nothing. Thank You.

 

Further to your left at the very corner of the painting

 

Does remind me a little of Steven Tyler though.
