Vintage individual shops ashtrays

A trio of 1960's vintage hand painted pink swans who were individual ashtrays. Can you imagine carrying a swan around in one hand while holding a cigarette in the other during shops a party? They would be lovely as jewelry holders or small snack bowls. They've been well washed and never used as ashtrays. Our mother had them on display in her kitchen since the day she brought them home. Made in Japan by the Porcelain Sterling China Company.
