According to the
Annual Report of the Director of the Bureau of Engraving and Printing For the Fiscal Year Ended June 30, 1919, Government Printing Office, 1919, page 46, 10,000 copies of all four sizes of the violet narcotic strip stamps were overprinted "Porto Rico."
Does anyone happen to have an example of these stamps?
If so, could an image be posted here please?
Thanks.
Jim
