It's been some time since I dropped in on Stamp Community. I published a second article about the Wituland stamps, "Wituland Revisited," which is posted at
https://www.academia.edu/63478245/W...nd_Revisited In that article I expanded on the analysis in great detail. My conclusion remains they are bogus stamps pasted in the 1930s on genuine pre-stamp covers or on thousands of pieces of paper of a variety of colors and papers.
A member asked "Where are the thousands of Witu stamps on piece that Farley Katz says exist?" In 1934, Robert Lerche, one of the "discoverers" of the Witu stamps and a dealer who authenticated/expertized many Behrens albums of complete used sets of the stamps on piece and published lengthy booklets about them, wrote that 2,330 used examples existed. In 1950, Dr. Eduard Ey published a census of all values and issues which total 3,357 used stamps. See table attached.
As shown in the table, at least 20 complete sets of all the 96 stamps exist, in used condition. The number that exist have no relation to denomination (high denominations often more common than low) or the time the stamp was supposedly valid (some stamps that were supposedly valid for a few days survive in numbers greater than stamps valid for about a year).
I found online images of some 244 used stamps on piece, the sources cited in the article. Currently, there are two different, handmade Behrens albums for sale online (one at a German auction house; the other
ebay Germany) each with complete sets of all 96 stamps, every one used and on piece, plus bonus photographs of additional stamps. Michel lists all 96 stamps in used condition, everyone on piece.
