Create 2 vouchers above each other, each for a discount of 100 CZK when purchasing over 1000 CZK on the e-shop called iUmeni.cz. This is a voucher for a discount on art books. Place the main text of the voucher "Vánoční kupón 100 Kč pro všechny čtenáře a zákazníky iUmeni.cz.". And somewhere in smaller text the text "Lze uplatnit pro nákup nad 1000 Kč". The motif should contain books and a Christmas motif, but a very discreet one. These are art books, so the voucher must be discreet. Make the voucher design as a black and white line drawing. Place the iumeni.cz logo in the voucher.
