Jeff,
It needs to be something from a personal collection, or one we can get permission for one time use on the cover and perhaps for promotion of the product. Don't think we can use the Blackhawk slide unfortunately.
We have a couple of goose shots that are not super prominent in the scenes, which is why I was asking about them. Also seen are #4, and one scene of #6. If you all know anyone who has anything, or museums that have collections let me know. For shots used there is a form of compensation.
We will also be looking for D&RGW NG and SG pics, but I have not begun to hunt for them yet, as I figure the RGS is the harder find!
