Vintage Pinarello Question: Decals

[DCilliams]

Does anyone know when Pinarello started using this head tube decal? Was it used on all their frames past a certain point or only on certain ones?

Apologies for the esoteric question :D

Sometime after '88 or '89. I have a Montello from '88 and it has the riveted badge but I have seen some ~'90 models with the decal on the headbadge.
