I am going to test the waters here for uploading and labeling images. Here is a nice selection of eye candy to share with the group.

89R2E Double Transfer with a probably 2 line precancel. If I recall correctly, the PF declined to comment.

1R2 KISS Double Impression (ex-saadi)

30R2E with a pre printing paper crease (With Amonette description paper)

10R2L Recut Button

6L0 with an Ultramarine Cancel

This is a Plum. It is not certified by any agency, but it was part of the color examples that Dr. Amonette created for William Litle with the PSE. I was informed by Albert Chang that Dr. Amonette had said that this color chart had the finest quality of stamps that he had ever assembled. There is what looks like a hair across the bottom of this scan, but it is a flaw on that portion of my scanner. :(

47L0 - 5 lines recut in the Upper Left Triangle. The only position on the Orange Brown's to exhibit this characteristic. This position also has 1 line recut in the LRDB.

I am sure these have been plated, but I do not see the notes at the moment. Hmmm. Either way, a nice pair with a NY SHIP cancel

Here is a pinkish variety - 91L5L, this is cropped. It has a large selvage to the left, as seen on the next scan.
Position 91L5L is a misplaced relief. Relief A on the bottom row is unusual. This position should have been a B relief. It is also a double transfer. And a pretty strong double transfer at that. Check out the Lower Right corner, in fact, the whole lower text label. it is easily visible in the UR corner as well. Especially from 2-5 o'clock on the UR rosette. This is a position and color that makes me extremely happy. :)

91L5L in Pinkish - with the selvage

Here is mint pair from the three rows of the left pane of plate 3 - Positions 39-40L3 - Certified as Mint, slightly disturbed Original Gum - but I can't see any gum disturbance. It looks Never Hinged to me.

This is just an unused block of 28 from the bottom of the right pane of Plate 5 Late.
I hope you enjoyed that little stroll through a few of my 1c and 3c 1851's. Since this thread is supposed to be a show and tell of these imperforate stamps, this should qualify.
Enjoy!
