Russo Japanese War Victory Ikeda Loyalty Association Army Navy Sake Cup
This is an antique Japanese military sake cup, decorated with a pair of flags, one with a cherry blossom (?) and one with an anchor. The words are "War Victory Commemoration" and "Ikeda Loyalty Association". This is probably a cup that commemorates the victory in the Russo Japanese war, although it may also be for WW1.
