Beatrice Cenci

Guido Reni painting the Portrait of Beatrice Cenci in prison.

The following versions of "The Portrait of Beatrice Cenci in prison" are probably the most obvious cases of variations that can be found with different canvas sizes and subject positions.
The clear differences are the position of the artist relative to the blue sheet on the bed and also the width and drape of the same blue sheet.    

The artists signature can be found bottom right in red.

The second version above was restored by Gatti Fine Arts Services.
