Thank you CultureVulture that last picture shows the detail perfectly.
It is unusual. Originally my thoughts were that it could have been Chinese or possibly Czech, however because of the completely flat and polished base I think probably neither of those. The only bud vases I have come across with that type of base are:
1) any of the Scandinavian countries, but the colours are unusually bright for those areas. Or
2) Japanese. Those colours are also 'right' for that area, so that is a possibility.
If you could let me know the circumference of the base around the widest part it may help me to eliminate another possibility, that of Hong Kong. As these have a similar look.
I will continue to investigate.
Cheers, Pat
