Here's an embroidered waistcoat from Unicorn.
The brand-name on the label is Artesania Pop Wuh.
I wondered whether this was anything to do with the Popol Vuh, a Mayan creation story from what is now Guatemala. According to
French Wikipedia, "Popol Vuh" can also be transliterated as "Pop Wuh".
And indeed, when I searched for
"Artesania Pop Wuh", I did find this image on Pinterest (apparently copied
from Ruby Lane), showing
a purple Pop Wuh waistcoat tagged as from Guatemala.
