Phosphorescent paper, no watermark, in 3 types:
These types as described by Chong for the Mexico Exportas series. The same 3 types used by Arturo de la Garza for the AyA series, but Arturo's type 1 is Chong's type 2. The Chong type 2 is also known as "American", type 3 is from Samuel Jones and has yellow fibers; type 1 is also from Samuel Jones but has NO yellow fibers... In the Mexico Exportas series according to Chong type 1 is only to be found for the 50c , 80c Ganada [WIFAG] and 3p shoes; Chong type 3 for the 50c and the 3p shoes. I have found the 4p Honeycomb with type 1 as well... |
