I believe these are all souvenirs you would have found at a little gift shop. These are from gateway Arkansas in the ozarks.

I believe the Indians are salt pepper shakers. No plugs in the bottom. There's a label on the one that says Lewis and Clark cavern Montana.  The rest all say Gateway Arkansas in the ozarks. There's a name on one. You can tell these are fairly old. I believe this family owned a trading post /souvenir shop at one time, based on paperwork found. Please look at pics for condition.  Estate find.
