Daniel F. Kelleher often features large worldwide collections, and their Auction 691 is no exception. Unfortunately, the only photos are almost all of the album binders. By way of example of what they are listing is Lot 822: "Worldwide, Collection, 1840-1953. 20-volume (A-Z) fairly new Scott International blue binders with Vintage reproduction archival pages printed on one-side only up to 1940 (albums and pages retail $3000), plus Scott International pages for Part II (1940-49) integrated in, with some countries containing additional pages...."
Harmer Schau also has a Big Blue Volume One in three binders in their APS Stamp Show Sale #110, lot 1670. There are a few photos.
UPDATE: Lot 822 realized $61,950 against an estimate of $30-40K. Lot 1670 realized $10,350 against an estimate of $10-12K.
