Hi,
The best book on the subjet is the (very) difficult to find Aegyptische Bronzefiguren of Gynther
Roeder. Mitteilungen aus der Šgyptischen Sammlung 6.
Berlin, 1956.
Otherwise any museum, with an
Egyptian collection and a
catalogue, may be a valuable source of information (The Metropolitan Museum, the British Museum, The Louvre Museum, the Museo Egizzio of
Torino, and so on ...
As an sample, I affix to this message a picture of an
Osiris Statuette from .. the archeological museum of Lisboa (
Portugal) !
Best regards.
