I finally got around to finishing up imaging my acquisitions from Chicagopex... a wide variety of early revenue material.
First a couple of documents...
This $1 Mortgage pair is a fairly tough item.

I'm always on the lookout for 1862-dated documents, and this one has lovely vignettes.

This one was pretty cool. The original issue of the stock predated the Civil War tax (October 1, 1862) so the front doesn't have a revenue stamp, but the transfer of the stock shown on the back of the document took place in 1863, hence was taxable. A nice mixed imper-perf usage with a strong SON cancel.

This cover is most likely philatelic, given the position of the two revenue stamps flanking the legitimate postage, although it's possible (unlikely) it was a double weight cover. Regardless, I found it attractive.

This one is aesthetically very attractive, an illegal use of postage as revenue on a large Illinois marriage certificate.

One of the things I'm trying to do is replace as many of my tougher stamps with examples on document. This is R135a, the vermilion error of color, used on document. This is a stamp you NEVER want to buy without a cert (this one has a 2009 PF cert).

And now individual stamps...
A nice RB11c top margin copy...

Even though this one has a large tear at bottom, the margins are ginormous! (R52a)

Ditto the margins on this one (R52a). The late cancel style raises some alarm flags, but I can find no evidence of trimming.

Who can pass up a nice margin block? (R35e)

Or a margin imprint pair? (RB4a)

Green cancels are exceptionally scarce. (R44c)

The only color more scarce is brown. (R62c)

An exceptional example of R56a... jumbo margins and a nice SON cancel.

GREAT contrast between cancel ink color and the stamp (R79c). Printing anomaly (ink smudge) at upper right.

A fantastic all-over double transfer on R15c, unlisted in Scott and not one I'd seen before. R15c is rife with major and minor double transfers.

I already have several examples of R5b with T5 major double transfer, but I simply can't pass them by, especially one with a nice SON cancel.

I've wanted an R33b imperf vertically (MUCH tougher than imperf horizonatally) for quite a while, so I finally snagged one.

I don't usually do anything with wine stamps, but I couldn't pass up a gorgeous double impression. Every example I've been able to find pictures of has this exact same cancel and date.

A *VERY* tough stamp, R112c (perforated 8). Finally got one. It has a pulled perf at left, but these come around so rarely that I figured I'd better snag one while I could.

And lastly, an R112b (sewing machine perforations). I already have several examples of the stamp, but I've only ever seen a single picture of one on complete document, and while this isn't quite the same, being only a piece, it is tied with a lovely "THE PORT WARDENS OF THE PORT OF NEW YORK" embossed cancel with a sailing ship in the center.
