I'd like to see a picture.

Probably about the time that the first good tyrannosaurid skulls were described
(1912 for Tyrannosaurus, 1914 for Gorgosaurus).
Incisiform tyrannosaurid premaxillary teeth had been known since the mid-1800s,
but there particular affinity was uncertain for many
decades (Marsh, for instance, thought they came from some otherwise unknown
large Cretaceous mammal).
