What 1912 Picasso work is often described as the first Cubist collage? Still Life with Chair Caning is the work.

Pablo Picasso made the oval composition in 1912 during the Synthetic Cubist phase. Instead of relying only on painted illusion, he attached printed oilcloth that imitates chair caning to the canvas. He also added painted forms, lettering, and a rope edging, combining ordinary materials with traditional art media.

The work presents fragments associated with a café or restaurant still life, including a table, glass, newspaper, and bottle. Its mixture of recognizable signs and flattened, overlapping shapes shows how Cubism challenged the idea that a painting had to create a convincing window onto the world.

Picasso is widely credited with making the first Cubist collage, although Georges Braque was also central to the invention of collage and had developed related papiers collés. The distinction is that Picasso's work incorporates commercially printed oilcloth and rope, while Braque's experiments often used pasted paper. Still Life with Chair Caning is now held by the Musée Picasso in Paris.
