This was a framed canvas print that I found at a home decor store. I added an older Mario and his hat (trying to match the uniform). I always paint in oils, and I'm pretty careful about what I'll paint into. I know that there are a number of people who really hate this sort of thing, but I do stick mainly to reproductions (framed canvas/board prints). Occasionally I will find some mass produced hotel art and use that, but I'll do my best to make sure I'm not ruining someone else's original work.
I just finished this one. The background was a knockoff of another very popular series of paintings that all looked very similar. It just screamed Columbia to me...
