Here are a few files that can help you with your hobby. I know some of the material may be dated, but I'm leaving it posted in the event it can be of help.
Not all of these are mine, some have been generously shared by other hobbyists to help all of us with the game.

Unfortunately, I've had to remove the downloads.
All that remains are the banner images below.

The Banner Project
Here are a few banners from a number of sources that you can use to create banners for your own army. It's as simple as clicking on the banner you want, saving it to your computer and using it as a reference to make your own.

Some banners are line drawings and others are colored in. The banners are larger than required to make it easy to trace them and then reduce them down to actual size for your models. In some cases, there are multiple banners under one image. The thumbnails are there to let you know who the banners are for.
