Rusty Nail on Old Beam

This nail, bolt, stud or whatever the rusty thing might be called, was piercing a very old beam outside a famous Cava (Catalan 'champagne') company which I plan to feature in coming posts. Being passionate about rust and textures in general, I thought this image was a good way to introduce tomorrow's story. Enjoy the week-end everyone! Don't forget the big picture! (click on the image)
