Oh, so very true! Many of the old school framebuilders were notorious for not rotating their stock. When a new stock of decals arrived, they would often be thrown in a drawer on top of the old decals. It could be years before the old decals got used up. And you often can't go by catalog pics either, as these were often made in early fall, using mock-ups, to ensure availability at the fall trade shows.

The company name change to TI Reynolds reportedly took place in 1977, so I'd assume that year was the introduction of decals with the TI reference, though it is comflicts with the OP's 1974 International decal.

The earliest objective case I've seen with the gold bar at the bottom was in 1974, but it may has existed earlier.
