#661 was issued with the following plate #'s
A first day cover of #661, dated May 1st, 1929. This was the first date it was issued at the Philatelic Bureau in Washington DC. The true first date of issue was April 16th, 1929, the day it was issued in Kansas.
Of the 130 photographs of Lincoln, the bureau chose this one as the source of their vignette.
The bureau slightly adapted the existing intaglio print engraving that they had had on file since the early 1880's. The vignette is somewhat changed from that used on #254, noticeably in the hairline.
To prevent the thieves from transporting stamps out of Kansas and Nebraska and selling them elsewhere, the Post Office tried overprinting the letters Kans. on stamps slated for sale in Kansas and Nebr. on stamps that were to be sold in Nebraska. All post offices in Kansas and Nebraska received overprinted stamps except for Kansas City, Topeka, and Wichita, Omaha, and Lincoln There larger post offices were not included as security at those post offices was considered sufficient. Higher values were not included as the overprints could only be performed by rotary press.
This was an experiment, which if successful would be extended to all states. These overprints would be valid throughout the United States. However it did not prove a success as many postal workers in the USA were not aware of these overprints and would not accept them as valid postage.
The overprints were commonly faked. The amateur simply used a typewriter. The professional fake was a bit more advanced. Here are some clues to a stamp having a fake overprint.
The faint ridges seen horizontally across the gum are called gum breakers. They were applied by the Bureau in order to prevent the stamps curling. Sometimes they are so faint they can only be detected by running your finger over the gum. The gum breakers on the Kansas and Nebraska overprinted stamps are 22mm apart. Which means only one gum breaker, or two if the breakers are at the very top and bottom of the gum, should be present. The example above is NOT an overprint as the gum breakers because the gum breakers should be further apart.
One of the most easily faked stamps, all one needed was a typewriter. Fortunately the period on most typewriters, at the time, was improperly aligned with the characters. The stamp above has a raised period, thereby it cannot be a genuine overprint.
An obvious forgery, the overprint is slanted, the plate number is wrong, the period is too far from the characters and the overprints are not horizontally aligned.
