European school (XX) - Figure stilizzate - XL format

I propose, in an auction without reserve, a stunning painting depicting stylized figures.
A work of excellent artistic quality, unfortunately unsigned, but it cannot be excluded that the painting could be attributed to a well-known artist.
Excellent overall condition.
Internal frame size 72 x 102 centimeters.
Technique: acrylic on cardboard.
The painting will be shipped without glass for security reasons.
Careful packaging and fast, tracked shipping.
