Ten main spokes radiate from the hub flanges, five on each side.
Each main spoke then radiates into a roughly 135-degree fan of nine
spokes to reach the gigantic rim, requiring five different lengths for
a full 9-spoke fan (spokecalc would go crazy).
So the wheel has either 10 spokes or 90. Or 100.
You can see two nine-spoke fans above the rider's head.
Here are two more versions of the same picture:

And here's a lady in the same contraption, with what looks like the
same buildings in the background:

She appeared in Eugene Sloan's "Complete Book of Bicycling," which is
to blame for this thread.
Presumably the advantage of this spoke design was that the high-count
nine-spoke fans supported the huge wheel better at the rim, while the
low-count five main spokes on either side left gaps large enough for
the rider to get in and out.
