Here are a couple of images from the Edgehill Unit Cards pack. The cards are designed by my chum Ian Notter, based loosely on the images in the Streeter Naseby engraving. Here is a page from the introductory pack that accompanies the cards, and, below it, an image of a sheet of the unit cards, themselves.
These are some of the Parliamentarian Edgehill foot; large units, eight ranks deep, so with an extra (fourth) hit. We have added uniform colours, where known (not often!), sometimes we have guessed. The flags indicate who the officer for the brigades is, and his superior general. All the information needed for play with For King and Parliament is on the card tab (save, ammo, battalion guns and so forth). If you laminate the cards, then you could use them with a whiteboard pen.
The whole Edgehill OOB, with lots of "what if" units, will be included in the download. Hopefully I'll have it in the shop on Wednesday or Thursday. If it proves popular, we will give the same treatment to some of the other battles of the ECW; perhaps we could produce a set of generic unit cards for use with the game.
