|  Type "D" of Pettigiani is better known as
"Holandés"
 Also the first occurance here is the 02.10.1939 Housing Congress stamp! The parallel watermark with symmetrical paper wire - English paper papel inglés - direction of paper parallel to the long side of the stamp "M": 
 
 The orthogonal watermark with symmetrical paper wire - Dutch paper papel holandés - direction of paper parallel to the long side of the stamp "M": 
 
 But is this the typical Holandés we know of the 1940 P&R I stamps????  |
