What is this blue mark on this (60s 70s?) sheepskin jacket?

hi Everyone, I'm wondering if this light blue mark is a dye mark/brand from the sheep. Is this unusual? Also wondering if this is 60s or more into 70s?
Thanks for any help.

Hi Lauren, I think that’s dye or coloring that rubbed off on it from something else.

It’s very cute and 70s.
