Simple art

We were walking down the street in Comer, GA....just past Colbert, GA and this door caught our eye.  I don't know who uses it or why, but I love what they've done with it.  I've printed it on a metallic paper and it looks amazing.  So, thanks to whomever.

what is art?

A couple of months ago I was in a gallery in North GA and in a back room that was not being used sat a nice, folk arty chair.  Not on display.  Just sitting there.  I liked how it looked against the wall and the rug, so I took a photo.  I really like how it turned out and the slight optical illusion effect, but mostly just the composition and the color.  Somebody asked me if it was ok to use another piece of art in my art....What's the answer?  I think the answer in this case is that I am not using the chair or even it's artistic qualities as my art, but the room, the light and the color and the presence of the chair.  I welcome feedback on this.
