Not exactly. It's common for the copyright date to not be in line with the official year of release. Just as the Bow N Arrow is said to be from 1990, it did not exist in pre-1991 packaging and was not in 1990 catalogs. It's all a matter of when in the year the product was released, and in the Slingshot's case, it's likely it had an early 1992 release given the copyright date.

I have no clue of its official release, though, so take my word with a grain of salt.
