From James Sanger:
I have a large lot that will be auctioned next week by Rasdales in Chicago. It has over 300,000 stamps. I have enclosed a summary sheet that follows directly after the Rasdales announcement. There are 20 boxes with 4-6 binders each packed with stamps. These are very well organized. This lot combines several large lots I acquired over the last 15 years. There is one box of literature with no stamps, with original ISGC newsletters and then El Quetzal. Includes some interesting things like Julian Grafs personal bound issues of the first newsletter and other ISGC communications as well as 2 copies of G-1 and announcements etc. from ISGC and the Guatemala post office on issues and some essays early that form basis of parts of G-1 and G-2.
Attached are his letter to me and lists of binder contents.
