Vintage John Lennon Imagine Artwork Carters Footed PJs 6 Months

In the 90s Carters partnered with John Lennon's estate for a line of baby clothes and nursery gear featuring Lennon's artwork. I got this in a hand-me-down bag, so I don't know the history. The tag has faded but it seems like 6-9 months. This is yellow and footed. It is in very good used condition, with some piling.
