The downtube decal is bogus. It's a Bridgestone 450. Looks like index shifters, so would be an 87 or 88 model. Note the neat Bridgestone self-centering brakes. Probably about the last year for those.

The seat tube decal may include some fine Engrish aspirational or inspirational prose or haiku. Report back what you find there. Some of them were ROFL good IIRC.
