Complementary pair of wrong backs from my 2nd 1949 LEAF set.
These inverted backs on the cards in the 2nd (SP) series tells us that the printer simply ran the pre-printed 49-card sheets (of fronts)
in reverse when doing the back print run. All 49 subjects in this series have been found with wrong-backs.
I've never seen 1st series wrong-backs from this set. Anyhow, if you have 1949 LEAF wrong-backs, please post them here.....Thanks.
