White Pottery USA Retangular Planter - STUMPED

Off White Pottery Rectangular Fluted Ribbed Planter Window Box
- found one that has an inscribed USA on the bottom but mine is not marked. We found one that had a Van Osdell's Leavenworth, Kansas foil label - could only find a Van Osdell's Flowers & Gifts so am thinking they may be a distributor

Flower box features vertical ribs on the bottom half with a smooth top portion. It has two concave curves/indentations on each long side and one concave indent on each end - a nice visual touch as the sides could have been made straight. It stands 4-3/8" tall and measures 5-3/4" wide by 3-3/4" deep.

Any help with the maker is much appreciated.

 

Here is the link to the one that has the Van Osdell's foil label.

Bumpity Bump. Do you think this is McCoy???

 

Kaudet, I recently posted an "unknown" USA planter, and Don ( @dgbjwc ) was able to ID it for me as BRUSH. Perhaps he can help with yours, too (?)

 

Thanks for the heads up @SBSVC . I'm leaning towards Shawnee for two reasons. First, the periods between the USA.are typical for that pottery. Second, they used those curved corners on a lot of their designs. I can't say for sure though. I checked my book but didn't see this particular design. There is a Facebook page on American Pottery Identification that could probably give you a definitive answer.

Thanks, Don! You're the best!
