Raoul Ch. de Thuin was a philatelic forger in the mid 20th century. His work is described in "The Yucatan Affair: The Work Of Raoul Ch. de Thuin, Philatelic Counterfeiter", compiled by a specialist editorial staff, an American Philatelic Society handbook. issued in 1974.

Raoul de Thuin was born in Belgium, but he moved to Mexico in 1931 where he became naturalized Mexican. He had his own stamp shop (Maya Shop), but also operated under different names: 'Gilda Rivero Mendozo', 'Thelma Salazaar', 'R.G.Knapen', 'Belgian Export company' and 'French Philatelic Agency' (source 'Stamp Collecting, February 3rd 1967, p 1007). He made many forgeries (mainly forged overprints on genuine stamps, turning them into rarities) of many countries, but he seems to have specialized in South America and specially Mexico. He also faked letters and guarantee marks as well. Though well documented, I did not see many forgeries of de Thuin (maybe because the detection of forged overprints is one of the most difficult tasks in forgery detection).

Most of his forgeries and equipment were sold to the American Philatelic Society (APS) in 1967. The APS then compiled the book 'The Yucatan Affair'. De Thuin then still continued selling forgeries from Ecuador, as can be concluded from the three letters from him to a stamp collector in 1973 (these letters were sold recently (2002) on E-bay, I have put '***' whenever I was not able to read the contents of the letter clearly):

Letter 1:

Raoul de Thuin
Sucursal de Correos URDESA
Guayaquil-ECUADOR Guayaquil. nov. 15-1973


I have duly received two kind letters from you and a cheque for
dollars $24.20. Thanks!
I call your attention you sent too much as, if my record is correct
our account is as follows:
Salvador, a fake (excellent) of Scott No75, priced $200 for $ 12.-
Three errors of the wheel set (double or triple) at $1.50... $ 4.50
Postage..................................................... $ 1.oo
Amount...... $ 17.50
Having received $24.20, I credit you for the difference and I own to
you $6.70
I examinated pages of old Gibbons you sent, being astonished how poor
is the listing of Salvador. Of course the most interestant are stamps,
postage and official, issued between i867 and i905.

Scott is listing along these years, postage stamps: 1120 and official
stamps 309........... Gibbons along these same years is only listing 252
postage stamps and 122 official.. Something unbelievable ....
Wheel set (Gibbons166-176) is a very interesting set, All small values
exist double and sometime triple. The 1 centavo exist in red and several
values exist with blue surcharge.
It is long years ago I got a true wheel having been used for these
surcharge and these I sent where made with the true wheel 40 years late.
On about set of Pedro Jose Escalon (i906) I will look in my stock if
be possible find something for you. This set exist perforated and unper-
perforated. The 2 cent. exist with double frame and several values exist
unperforated between stamps. In the same issue surcharged, them exist
several errors in surcharged, (1909).
Answering to thepart of your letter asking if I have rare old stamps
on covers, yes I have as the followings: excellent fakes on covers:
Roman States 50 bajocchi and 1 scudo - some old Switzerland and Germany,
bisected old English colonies and Mexico. All more or less at $10 each....
I have too excellent fakes of rare Buenos Aires 1858 and 1859 at $6-
each single or at $10- on covers. Same price mint or used.. It exist in
this set three tete-beche: the 2 reales of 1858 and three reales of 1858
and too the 2 reales indigo of i859. These tete-beche are counted as two stamps
For send on approval these stamps on covers to your friends, I want
$100 in advance no for distrust but for be sure it exist a want to buy and
not only a curiosity.. I am an old man and I want to liquide all it stay
in my stock and take my rest along want it ******
My own language is *** I am daily speaking daily spanish for be married with
an Ecuatorian lady. As you see my knowledge of english language is very poor.
However I hope you will understand **************
