This item was included as a visitor gift when purchased at the National Museum of Nature and Science a few years ago. I couldn't find any information about it online, so I don't know much about it, but I think it's a rare item. It has the same embroidery as the blue whale object in front of the museum. The size is adjustable, so I think both adults and children can wear it.
