Vintage 80s toddler sweater 3/4 JJ Poole Gymboree style

I love 1980s knits! Vintage 80s acrylic sweater, by JJ Poole. Fun primary colors. The chest is 13” across and length from shoulder to hem is 15”. Approximately a 3/4 or 4t in my opinion. Very good vintage condition, no flaws to note. No pilling.
