Greg,
I guess you got the news on Whitney from Dave, a great teacher and friend, seeing Howard & Whitney collaborating on a flag project was like watching kids on Christmas morning.
If you go to The Flag Heritage Foundation web site they have a good picture of the Foster Flag. They also have a gallery of other flags that you might be interested in.
Happy Trails!
