Paraguay is somewhat unusual in that although a few regular issues between 1869 and 1881 were forged, the emphasis was placed on the airmail issues between 1929 to 1937.
Most collectors think that forgeries are relegated to only older expensive stamps however Paraguay is proof that this is not the case.
There is not a lot of information available on these but my research and finds indicate that probably more than one forger was responsible as there are very good forgeries and some that are somewhat crude.
Based on my research, forgeries are often found with postmarks which may indicate that the purpose of these forgeries were postal in nature..
We will do a side by side comparison.
