Overprint On Manchukuo Stamp And Date Stamp Created/ Second Stamp Without Overprint

I have two Chinese Great Wall Stamps that I need an ID of as to dates of creation and overprint reading, as for the overprint I understand that there could be a character that may mean it is a special stamp. The second stamp does not have an overprint but it contains marginal markings is this special?

Thank you

Not sure where Manchukuo comes into play here. These are Chinese stamps. The overprint actually looks like a revenue marking. The bottom stamp retains its selvedge with printer markings. It is known in the hobby as an "imprint" copy. Neither have any premium above catalog value as far as I know. The selvedge stamp may be of interest to a specialist though.

The full inscription at the bottom of the sheet would be "Chinese Bureau of Engraving and Printing"

1912 Great Wall Issue

In 1908, Lorenzo Hatch and William A. Grant brought expertise from The
American Banknote Company to start the Chinese Bureau of Printing and
Engraving. The initial design options were the "Temple of Heaven" and the
"Great Wall Guard Tower".

The first design that was put into general usage in 1912 was the Great Wall design, printed and used by the Republican government for five values: 1¢, 2¢, 10¢, 50¢, and $1. The basic design was used through the 1920's with many new and "touched up" dies at many printing locations. This led to many minor printing variations and color shades.

Overprints were applied by provinces, cities, local groups, and Chambers of Commerce with many sizes, colors, and arrangement of characters. The 1¢ and 2¢ values are quite common with these "chops."

The Great Wall series wide-usage created logistic problems in having the quantities needed in many locations plus having secondary operations (overprinting).

The Wheat series was created to have provincial identifiers as part of the initial printing. This resulted in less overprint variations, est. 1,000 versus est. 15,000 for the Great Wall series.

Your overprint is one of the 15,000 variations for this Great Wall stamp.

I cannot read Chinese to translate it, but thanks for sharing it with us, nice pair of stamps.
