coffee brewing machines - graphics

Way back when I made the coffee plant tattoo I also made these graphics, where I illustrated different coffee brewing pots and machines. I know the other one was a tattoo design, I don't know if these were too, or they were just graphics the client wanted for his speciality coffeeshop, but nonetheless, I think they'd look good either way. Now, I couldn't tell you what each one is used for (maybe you could tell me?), I'm just the artist here. I'm kidding, of course, I did research on each one when I drew them, what? You think I'm stupid? Anyway... Enjoy this cup of art. Ha!
