I have observed, but do not own, Empire Express labeled 1927 Bluebird and Jeffersonian sets. Therefore, I suspect that the full 1927 electric line was likely sold as Empire Express labeled sets.
Have not observed very many of the 1928 electric sets with Empire Express labels.
One obvious Empire Express set from the 1927-1928 era is the Standard gauge set, which I do not own. I have seen a couple of these sets in their original boxes and oddly, the boxes featured regular American Flyer labels. These sets are associated with JC Penney.
Another obvious 1928 era Empire Express item is the airplane, which to my knowledge was not associated with JC Penney.
