Myself and other advanced Exhibit card collectors have been working on year by year checklists for the Exhibit cards.
As pertains to your question about the Jackie Robinson card he was issued every year from 1948 through 1956. Including the 1952 B&W tint and the 1953 Canadian Exhibit set in both purple and green tint and both 1955 Postcard back sets. The plain line and the A MUTOSCOPE CARD back.
And to give you a real headache he is also in the rarely seen Pittsburgh Post Gazette, and the Miami Fun Fair Exhibit sets as well.
The good news is he retired well before the extremely rare 1959 Dad's cookie set was issued in 1959 thus he is not in that set.
Another possible back is the Triple Nickle shown below as well as a, ready for this??, set issued in Puerto Rico called the Bomba Chiclet set.
And finally.... there is a good chance he also was issued in one or both of the M.J. Holloway& Co. Exhibit sets. I have never seen a Robinson with this back. Maybe someone here can post it. However looking at others in the checklist for the set it seems they were issued i 1947/1948
Sorry for all this info! Aren't you sorry you asked?
If you need to see the actual Jackie card in the purple Canadian or the the other Holloway back LMK
