popular ! Lot of Vintage Native American Pottery Vase/ Containers

I don't know mucu about these, unfortunately, bc it would be a really neat thing to have knowledge of.

I saw Sioux, Navajo, Native American, and Mexican when I tried to find any information on these. They all have markings, I can only make out Kowboy Navajo and Little Thirds? Like I said, I really wish I knew more. They are clay pottery, non glazed, pastels colors with various designs, lines,and symbols. As pictured ,here is a hahairlinerack at the top of 1 vase and numerous scuffs on all. I used a dry erase marker on my own personal piece like these and it took the scuffs right off without affecting the design - I am leaving that up to the buyer :)

Sweet set, ready to sit in your window sill, grace your dresser or office desk. Could be gifted also to someone who collects pieces prefer these, I feel like that would be a really thought and special gift.

They vary in size:
8 1/2 inch vase
5 inch Kowboy Marking
6 1/2 inches Little Thirds
4 1/2 inch Blue Stripes
