The Greek Wedding Keepsakes

There are two of these dolls in my collection, one is white and the other one is pink. The lady doll can be split into two parts and inside there is an inscription on a piece of paper; Michael-Kate 8/3/59. I think these dolls must be the keepsakes from the groom and the bride on their wedding day to the guests who came to attend their wedding party. There are a lot of Greek migrants in Australia. Michael and Kate must be their adopted Australian names.
