Paraguay 1918 40c Ocelot with Inverted Overprint, Block of 4

Paraguay · 1918 · 40 Centavos

This stamp features a detailed illustration of an ocelot, a wild cat native to the Americas. It is part of a 1913 definitive series that was later overprinted in 1918 with 'HABILITADO / EN / 40 / CENTAVOS' to revalue the original 20 Centavos stamp. This particular block of four is a variety where the overprint was applied upside down.

In the early 20th century, Paraguay, like many countries, used overprints to quickly adapt its postage to changing postal rates or currency valuations without incurring the cost and time of printing entirely new stamps.
