The Aviation Heritage Centre at Omaka, Blenheim, New Zealand, has published a fantastic calendar for 2008, called "The First Warbirds".
Measuring 430mm x 305mm in size per page, and superbly produced, it features air to air and ground to air photos of the aircraft from the Vintage Aviator Ltd collection (i.e. the famous WWI fighters from Omaka and Masterton here in NZ) as well as a couple of shots of the displays inside the AHC itself.
This has been produced by the AHC as a special fundraising effort with proceeds going towards the Aviation Historical Centre's expansion plan, so it's all in a great cause.
You can check out more about this calendar including several of the photos on the photographer Gavin Conroy's website here:

You can only purchase this calendar from the AHC directly at The Aviation Heritage Centre, PO Box 641, Blenheim, New Zealand. The price is NZ$25 plus postage and packaging - a great bargain
