These two are the Greek equivalent of the famous Turkish puppets Hacivat and Karagoz. In Greek they are known as Karaghiozis and Hadjiavatis.
Karagoz (Black eye) is the poor but smart hero of many well known stories where he gets the better of his friend Hacivat and a series of other characters.
These puppets are full sized (48 and 52 cms long and approx 20 cms wide) and come with metal sticks which are used to hold them against the lit screen. They are made from a stiff painted acetate.
