Some of the designs are pretty standard (plain monks, half brogues, etc.). Others are unique to the Flusser store, so far as I know. For instance, there is a dress slip-on that looks just like the shoe on p. 197 of Dressing the Man
; I haven't seen that anywhere else. There is a loafer that looks just like the shoe on p. 196 (essentially a penny loafer with no slot in the vamp decoration). There is also another brogue slip-on with a very short vamp that I think is unique to the shop.
The shoe on p. 196 looks like EG's Buckingham model, and the one on p. 197 looks like EG's Atlee model:
I've never seen either one in person, though. I rather doubt that they're the most high-volume of EG's models. Regardless, I'll have to check them out the next time I'm in New York. The last alone would make it worthwhile, and the possibility of new and interesting models, leathers, and finishing is just icing on the cake. Thanks for the description.
