T206 Backs set

The other 3 super-prints are shown here (Cobb and both Chase's).

The super-prints are both 350 series Subjects and 460 series Subjects. There is an observable difference
in the green ink used to print these super-print's 350 vs their 460 backs. However, it is not as significant
as the difference that are seen in the 150 Series backs and the first 140 Subjects in the 350-only series
versus the 62 cards in the 350 series with the "apple green" backs.

Apparently, American Lithographic started printing the SOVEREIGN advertising backs with darker green ink
in the 150 and early 350 series cards. Then used lighter shades of green ink for their latter 350 series and
the 460 series.
