SET OF FOUR CARDS / duplexed & die cut/ 4 colour back variations

here is mock up which uses the colours of the axis to create a set. the appropriate axis will be die cut to show through the colour of the duplexed stock.

however after further development of the mockup, i feel that use of the die cut is unessesary for the the business cards and will work better on a set of flyers.

this will allow me to use the die cut and duplex on a larger format and therefore come up with some interesting compositions.
