Since I've been dabbling in 1st-2nd issue bisects on documents, I've decided to put together a rudimentary revenue bisect "census", putting together as comprehensive photographic list as I can on the known examples. I've pulled as much as I can from the Philatelic Foundation archives, Stamp Auction Network, Siegel, Shreves, Kelleher, and Eric Jackson's auction archives, along with the material from my collection.
http://www.revenue-collector.com/bisectsIf anyone owns examples that are not already shown, or has auction catalogs that show examples not on the above page, and wouldn't mind contributing images and information of what they have, I'd greatly appreciate it.
Thanks,
