Ah good, glad it worked. Unfortunately the PDF is only the bitmaps of the images - it'd be smaller if I used the vector data. I should have included a ruler for size with the photo. However - each card is the standard poker/magic/battleground size of 2.5x3.5 inches, the layout is about 4x4.5 cards so is 14"x16" in size and does take room - this could be fixed with either smaller cards, or a larger overlap on the cards. If you want separate 300DPI images, or the photoshop file, let me know and I'll put it on my site as well.
You could just have conditionals written on the cards - "only build if..." and just lay the cards out in neat overlapping columns like solitaire/klondike to take up less space - but that is not very visually appealing.
However - a tuckbox for the faction's kingdom could store the cards between campaign turns, putting just the building cards in that you have built. But it does mean packing and then setting up between each campaign meeting.
It would be good to have faction themed cards - it matches the idea of baggage/camps for DBA/DBM that match the army, or the different building structures for Starcraft, Warcraft or other RTS games.
I've only got the High Elf cards, but have Kingdoms (and Mercenaries and the Terrain) on order - so I've not tried to do any artwork for the cards yet
