In January Todoroki-san made a few references to Art Flick flies in his post about the Catskill Kebari.
I found a couple of links to Mr. Flick’s flies on the AMFF website.
I’d guess most of them would be in the class of Futsū kebari [ 普通毛鉤 ] in Japan.
Pictures of a few more, that were sold on Vintage Tackle website.

A bit more about him from the Catskill Visitor’s Center from a few years back.
