Tom,
Yes, indeed, Whitney was there! And I recall one specific item that he got from them - a WPA (ca 1934) collection of silk-screen prints of flags of all nations. I also have a copy of that collection, minus the flags of the US and UK, but we all know what those look like.

I think Whitney traded them a certain number of years of his Vexillological Services for those books. What a deal!

I tend to remember that meeting as I was president of NAVA during that 1994-1996 time frame.

We are having the International Congress of Vexillology in the D.C. area in August of 2011. I will post an annoucement on this forum in the near future.
