The chart is printed on extremely luxurious, 3mm thick board. This is like the thick card on the back of sketch books so this chart will prop on a shelf, look great in a frame, or can be punched with a hole to hang up. It’s a single sheet of card, with the chart on one side and plain colour on the reverse.
The dimensions are 148.5mm wide by 420mm tall. This is the same height as a sheet of A3 card but only half the width.
