Who made this?

Greetings,
For the past 40 or so years, my mother has been collecting pottery, usually small studio stuff.  Anyway, she's now begun to "unload" it on my sisters and I.  Any guesses who made this?  Thanks so much...

Welcome to the forum. We don’t give valuations so I’ve removed that reference from for query, although I will say that an unidentifiable pot is of decorative value only.
I’ve reloaded your photos here as thumbnails so they’re easier to see. I haven’t seen any marks or signatures on your photos, so I’m assuming the potter didn’t mark it. Unfortunately that will make it very difficult to ID unless someone has the same pot.

Naomi is right as always. Over the past 60 years there have been thousands of competent potters who could produce work such as this. Many just used a sticky label for identification, and that soon disappeared. Impossible to say who it is, without a specific mark, as it is so generic.
People collect studio pottery because it is cheap, but also usually incredibly well made, and a pleasure to have a lovely decorative item made by hand. Its a nice piece, and your mother has very good taste.
But...... Of all the studio potters there have been, only a very small proportion are worth anything.

If & when you know the potter then check completed listings on ebay for an idea of value. Unsold listings means the seller has over priced their pot.

You could ask your mother if she remembers where she might have bought it or if local to you in Maryland then you could do an internet search for say "Maryland pottery" and similar searches, which might bring a result.
