These white metal buttons are reproduction buttons which I purchased in 2010. On the left is one from 1900-1910, the middle one 1860-1899 and the right one 1941. They were made in Italy and I wonder if the original moulds were used. They were produced under the La Mode brand. There was quite a series of them produced at the time and I saw them advertised in a craft magazine and it took some time to track them down. I eventually got them in a craft shop in Bendigo and was so pleased to find them.
