Can anyone tell me where to get more of these (Artwork)

[Common_Courtesy]

I bought these back in 2010-2011 from two different street sellers in Kefalonia and Zanti and I really want to get a few more but i have no idea where to look,so if anyone has any idea where to start or even better where to get some then I would appreciate it, you can also have a cookie. 

 

2010 

   

 

2011(Lol my wall looks pink) 

 

There are some initials on the one I bought in 2010, I can't make out the first letter but i think its something like B.R. Although seeing as a year later I saw another street seller selling pieces 

 in the exact same style on a different Greek island I doubt he is the original artist. As I said any help with this would be appreciated.
