“Contrails (short for “condensation trails”) or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets or, if the air is cold enough, tiny ice crystals”. – Wikipedia

Tattooist Jay Freestyle, who is based in Amsterdam, creates what only can be described as works of art that last forever on his clients' skin. His style is freehand – without any sketch or stencil and he inks the incredible drawings straight onto body parts. They might look expertly planned, but the swashes of colour, detailed line work and geometric shapes are all the result of some clever improvisation. Photo: An amazing example of his mixed style.
