5rin imitations ... warning

Wada Katoro did not produce any ... and Maeda Kihei has been identified as designer of one position grey-black koban ... however, looking at the 25 position spiro sheets : 3 16-petal kiku sheets exist ... that I would class as troublesome to the collector ...

close examination of the kiku design , and comparison to the genuine is required ... on the left is a spiro-kiku; on the right a genuine-kiku design. in the imitations, normally a dot appears in the core ... also the petals are mishapen ...

note the variance in the oval frame designs ...
