REGISTERED CANCELS
The registered rate for mail at the time was 5¢, and as a result a good number of these stamps have the registered cancel on them, a typical example is shown below. This does not detract from the value, unless, of course, the strike of the cancel is heavy, which they often can be.

The Dept. of Bureau and Engraving were determined to depict Frémont in the Rocky Mountains on one of the Trans-Mississippi stamps, nobody knows why. Of course John Frémont was delighted at the prospect and sent the department a bunch of photos of himself. These were politely declined. The engravers had to resort to the only three renditions of Frémont in the Rocky Mountains. The first was a John Frémont campaign poster and the next from a biography and the other was from a Scholastic Text Book

The Frémont Campaign Poster of 1856
(one of the three sources of the design)

An engraving from the biography
'The Young American's Life of Frémont' by F.C. Woodworth
(one of the three sources of the design)

John Bigelow's woodcut in Scholastic's 'Memoir of the Life and Public Services
of John Charles Frémont, the third source for the design.

The campaign poster (above) shows a bearded trapper and a Mexican waving at the Colonel. On the stamp design this was changed to a soldier and a frontiersman. The original can be found in the Library of Congress. The idea for the background mountains came from the Bigelow woodcut, also shown above, you will see that the stamp design shows the position of the flag and Frémont reversed. The design for the top of the mountain mimics the illustration from the biography (middle picture above).

There is a somewhat scarce Light Blue color variety to look out for, I cannot find any auction records of one being sold. Brookman refers to them and the only example I have seen, that remotely looked like this color, was a torn up copy sold on ebay.

This design was originally planned for the 8¢ value, then the 2¢ value, before deciding on the 5¢ value.

The original bi-color design.
The bi-color design had to be dropped as the bi-color printing process
was taxed to the max printing revenue stamps for the Spanish-American
war that had broken out.
