My 2 favorite T206 backs are the
AMERICAN BEAUTY 460 and the
UZIT. American Lithographic printed
74 subjects with these
backs at the tail-end of the T206 press runs (Circa early 1911).
I refer to these T206's as "TWINS", since these 74 subjects appear to have been printed simultaneously with both of these backs.
As rare as these UZIT cards are, listed here are the two levels of scarcity you will typically experience searching for them.

. . . .
Level 1
A total of
60 subjects with the
UZIT back have been confirmed as of Jan. 12, 2023.
I am confident that this list of 28 in the
350/460 series is complete as it coincides
with the confirmed list of 350/460 series subjects with
AMERICAN BEAUTY 460
backs.

Level 2
The most difficult UZIT's to find are in the group which I refer to as the
Exclusive 12 in the 460-only Series.
To date, only 5 of these 12 subjects have been discovered with the UZIT back.
