Chile : 100 years of the Publication of Chile's fauna and flora by Claudio Gay - Intro

In December 1948, Chile issued 3 series of 25 stamps, dedicated to the work of Claudio Gay, who published his work 100 years earlier.

Each set consists of 25 stamps with local fauna and flora.
The 25 stamps are issued with a face value of 60 centavos, and then repeated with a 2.60 pesos-value, as well as a 3 pesos-value for air mail.

One full sheet contains 4 sets of 25 stamps. So there are 100 stamps issued on each sheet.

Counting from left to right and from bottom to top, stamp 1, 6, 51 and 56 are the same.
Also 2, 7, 52 and 57, and so on.

Luckily for us - collectors - there are some plate errors that occur on several positions on the sheets.
There are errors on the 60 centavos issue (Mi : 362-386), the 2.60 pesos issue (Mi : 387-411) and the 3 pesos (airmail) issue (Mi : 412-436)

In the following posts, I will show and explain some of the known plate flaws and their positions.
