That's 'Crippsii'. Resembles 'Shishigashira', but is less distinctive.

BB boy may be right but this tree has an canundrum for a name.Della of Jd's backyard nursery got one a while back and we did INTENSIVE reserch on it with little luck. Evalds lists it but with no info and the photos didn't look life hers!! ...Not much in vertrees. Now i see a blurb in Van gelderens maples of the garden comparing it to AP Shishi gashira. and having been introduces at Hilliers in england in 1928...The photo DOES NOT look like evalds or Dellas trees or sound like yours...and it considers it a dwarf shub...not your description !!!My guess is you will never ever know cause the name has probably been spelled wrong at some point, as vertrees says often happens,or mislabeled or both and it may in fact be a crispa or crispun ( both in maples of the garden also and vertrees book) or whatever. I'd buy this at your own risk ...if its cheap ...go for it if it's more than a generic seed grown ( coin flip) maple its size I'd pass....David

I believe the photos currently on the Esveld site to be accurate enough to give you an idea about what the tree should look like. I would compare it to Okushimo or Ojishi--but as bboy says, not as distinctive. A small green leaf with pointed lobes that have rolled margins. The fall color will likely be yellow with posibility for some minimal orange. I would not expect it to reach 15-20ft for many years, but 10-12ft after 10-15years.

Acctually, if you were to compare it to the photos of the Okushimo on the same site, it seems hard to distinguish.
