I thought this would be a quick and easy prop to make to display along with my sonic screwdriver... but I've not been able to find the correct wallet/id holder/credential holder. Here's a screen-cap of the wallet with the paper: (thanks to WackyChimp for the hosting.) Looks like black leather with a plastic window for the paper. Notice the little "pocket" inside the bottom? I've lightened the image a little so you can see it better. After days and days of searching, all I've been able to find are ID holders with the plastic windows on both sides, not just one. See this one for example: (again, thanks to WackyChimp.) Any help or leads would be appreciated.
