Ugly 1960s art pottery makers marks identification needed, please.

As title. I recently bought a job lot of stuff because there was an antique book from the 1770s in there I wanted. The lot included two pieces of ugly 1960s pottery. It's the sort of thing that's either worth a lot of money, or sod-all. I know nothing about the subject, but there's such a breadth of knowledge of various things on the forum, I thought someone here might know.

Knowing absolutely nothing about this sort of thing at all I'd say it looks dreadful, pants! On that basis, it's headed for the bin.

Looking forward to a real answer!

I have a collection of Fosters pottery which a mottled Brown. Can't say I know this who or what this brand is though personally I quite like it. Might be worth taking to an auction house, they might have someone who can tell you what it is.

A quick update with some photos of the rest of the pots:

I have quite a collection of "ugly art pottery". No idea on maker but I have some German postwar pieces that are similar.

Try "Kandern Keramik" for the KK one, that could be German.

I like them.

I have no knowledge of the marks but going by the design I think they could be Czech.
