Wipa 1911 Cinderella Advertising Stamps. 10 Or 11 Colors

I have a set of 10 different colored Wipa 1911 cinderella stamps. Designed by Koloman Moser and engraved by F. Schirnbock. Very good quality engraving and printing. look at these stamps under a magnifier and you will be amazed by the quality. My question is as follows. are there 10 or 11 different colors? Kind regards, Johan.

Johan, according to http://ephemerasociety.org/3/groten...ASDA9-08.pdf these came in 11 colors.

Thank you Peter.

I have seen this article. A very good article.

I came to my question for the following reason.

I have the set twice, unused as shown and a set with the wipa cancellation. both sets in the exact same colors, which would mean that I am missing the color 11. I also wondered about the number of 11 colors that sound a bit unbalanced. you presume that they would issue 10 or 12 colors not 11? Could be that the essay/proof shown in the Groten article is considered as the 11th color. Maybe somebody owns a complete set of 11 and can show us this set.

Johan.

Johan - Comparing the WIPA 1911 cinderellas in your post with those on the postcard in http://ephemerasociety.org/3/groten...ASDA9-08.pdf
I would say you lack number 2 in line 1 and number 1 in line 2 on the postcard.

Hi Florian,
link not working here.

Hello Rod,

Sorry but it is the very same link as that posted here yesterday by Petert4522

Thank you Florian,
Peter's link loaded OK

Marking the 10 cinderellas shown by Johan with Arabic numerals 1 - 10 and the 8 ones on the postcard with Roman numerals I - VIII,
I assume that
No 1 = No IV
No 3 = No III
No 5 = No VIII
No 6 = No VI
No 9 = No VII
No 10 = No I
Nos 2, 4, 7, and 8 do not seem to appear on the postacard
while Nos II and V on the postacard do not seem to appear among those shown by Johan in his post.
