How did Picasso create guernica?

Picasso found a studio big enough and began to paint behind closed doors. In the first few days, Picasso drew 25 sketches in one breath. Only two people are allowed in. One is the poet Ai Lvya, whose comments are full of passion and can stimulate Picasso's imagination. The other is Picasso's new girlfriend Dora? Mar, a painter and photographer, used a camera to record the constant changes of this work during Picasso's creation, so that future generations can understand Picasso's thinking process when he specifically expressed his fantasy.

When Picasso finished the last stroke, the whole painting was 349.3 cm wide and 776.6 cm long, reaching the rafters of the roof beam. The house is big enough, but it's still a little difficult to fit the picture. You must tilt it back a little before it fits. Every time Picasso modified the upper part, he stood on the top of the escalator, as if he were working at high altitude.
