In the lead up to Christmas, Casemate is giving away the complete set of all four books in the Past & Present series for just £30 instead of the regular £40.

The Casemate Past & Present series reconstructs historical battles by using photography to juxtapose modern views with those of the past. Highly illustrated they offer an overview of important battles, divisions and places, and include specially commissioned present day aerial views. The books present a coherent link between now and then, linking the monuments and battlefield relics with what actually happened.

To apply your £10 saving simply add the four books to your basket on the website and then enter voucher code PANDP2017. Offer lasts until end of December 2016.
