The latest poster from Pop Chart Lab isn't just beautiful—it's essentially a visual cookbook featuring eye-catching combos for over 90 sandwiches. The lunchtime staples are divided into categories based on main meat (or veggie) and then broken down into their various delectable constituents. A handy notation guide offers up info about serving temperature and country of origin. Perfect if you really love a good Reuben, chicken parm, and BLT—or if you just regularly find yourself bereft of culinary inspiration.
