From the late 90's pushing Y2K where they had changed their branding tag but were still making some pieces in Guatemala. Tiny baby overalls are the cutest thing in existence, plus with your overflow of onesies these are perfect to throw over any number of things! Size 0 to 3 months, I would say that's pretty accurate with maybe a little wiggle room past 3 months. Great vintage condition.
