A network of shells of various colors and thus stellar populations around the ETG NGC0474. True color (combination of g and r bands) image obtained with the MegaCam camera at CFHT as part of the Atlas3D project, and processed by Coleum.

This system is discussed in Lim et al. (2017), who present evidence for the association of globular clusters with the shells.
