I got in an argument with my boss about this picture. It shows Pablo Picasso, there is a plate of Paella on the table, so I assume this picture must have been taken in Spain. He seems to be smoking some sort of cigarette or cigar.
Now my boss claims that Picasso in this picture is talking to the guy on the right, which is supposed to be a spanish Matador (I don't know where he got this information).
I claim that Picasso isn't talking to the guy visible on the left, the blurry one with the open mouth. I don't think so, and I need to prove it somehow because 6 other people supported his claim to be true. I need to know if my perception is distorted or not. In my opinion, Picasso isn't looking at the visible guy, but to the guy right next to him. To that guys left, to be exact.
I tried to find the source to this picture, to maybe find out more historic details about it. But there seems to be no source at all. I tried google reverse image search and tineye, everything just points to some kitchen manufacturer, but not the original source of the photography. Some french journal shows more of the picture and I think the source is printed on it in the right bottom corner, but it's just a preview and it's too blurry to read.

I think by finding the source, I might find out what exactly happened in this scene. Who picasso was talking to, to be exact. I also plan to find out if there really was a matador present on this table.

Can you help me?
