 Forgeries

These forgeries are very common and aside from the large margins can be dangerous. Note the corner circles that often touch the outer frame.

These are quite rough with the bottom letters too large.

These are from Fournier (my Geneva catalog)

The letters "FRANCO" are too short.

The smoke is thinner than the original.

A partial block from Fournier

The following are all from Sperati.

1 P Sperati forgery, Reproduction 'B'. There is a very large blue spot in the white space below 'S A' of 'BUENOS AIRES'. A similar spot can be found just above the front mast of the ship.

There is a red dot in the upper left white circle of these Sperati forgeries of the 4 p values.

This 4 r Sperati forgery has a brown dot in the upper left white circle (as in the 4 p Sperati forgery)

There are two dots of color in the white space below the letters 'UEN' of 'BUENOS' in these forgeries of the 4 p values. The first 'R' of 'CORREOS' also has a color dot in it.

Sperati forgery of the 2 r blue value. The second 'R' of 'CORREOS' has a curl, the 'S' of this word is broken. The word 'DOS' shows defects: broken top of 'D', break at bottom of 'O' and lower part of 'S' broken. Note the dots in front and behind the 'F' of 'FRANCO'. The central oval is broken below the left part of the first 'R' of 'CORREOS'. A coloured dot appears in the white line above the 'E' of 'AIRES'

Possibly Torres

Note the inverted "N" in "BUENOS"

Cancels typical of Torres

All values written as "FOUR" instead of "CUATRO"

These are Latour reprints, made with stolen printing plates around 1912. They exist in bogus colors and in several types. The American philatelist Alfred. Lichtenstein obtained the plates later and made further reprints.
