Dr. E.L. Soule introduced his Oriental or Soverign Balm Pills around 1848. In the early 1860's rights to the product were bought by Elson T. Wright of New York City. Wright was able to gain permission to have a proprietary stamp incorporated into the wrapper for the pills, and these were issued from August of 1863 until April of 1867. 275,518 were issued, all on old paper.

Sometimes only the top part of the wrapper is offered as the stamp. This is nothing but a "cut square" and would be worth much less than the full wrapper.

In 1866 the product was sold to A.N. Wright of Syracuse, New York. The main design change was the address to the left of the wrapper. The new ones were issued from May of 1867 until May 31, 1876. 275,216 were printed on old paper and 163,534 on silk paper. The copy shown is on silk paper.

Position 1 on the plate used to print the Soule wrappers contained a foreign entry consisting of remnants of the Xavier Bazin perfume essay. This persisted through the various printings of the wrapper. The copy above containing the foreign entry has the Syracuse address, and was printed on old paper.

The most noticeable remnant of the Bazin stamp is a blue line running left from the upper left corner of the D in "Dr." Other small dots of color are present, and a short line can be seen crossing the upper part of the E in the left manuscript signature.
