They're just lettering, not really a decal set...
Greg Softley from Australia has some more complete ones; I got a set for a Pinerello I have, but haven't used them yet:
+1 on Greg Softley. Excellent product.
ISO: Lejeune Champion du Monde Ultra Leger Reynolds 753, 53-55cm
+2 on Softley. Got a set for my Treviso.
