Screen printing is a very old technique.
These days it has evolved into a highly complex procedure that produces some very fine work.
There can be as many as 40 separate colours added one after the other until the picture is complete.
Most of this work is completed by hand, and for this reason it is often said, that no two silkscreens are exactly the same.
Lowland gorillas is exactly as the name implies,
the great creatures inhabit the lowlands on the country.
They have developed highly sophisticated and complex ways of communicating with each other.
