The god Ptah-Sokar was a composite of Ptah from Memphis and the falcon god Sokar.
By the New Kingdom the triad Ptah-Sokar-Osiris was composed.
Figurines of them were put in the tombs looking like a mummy-shaped man with the sun disk, ram-horns and plumes or the atef-crown. These statues often contained a copy of spells from The Book of the Dead.
Ptah-Sokar was mostly seen as a man with the plumed crown and carrying the ankh-sign and sometimes the big staff with the dejd-pillars belonging to Ptah.
