Unusual Design Tachi Tsuba (Thoughts?)

[Winchester]

Thank you in advance for any feedback or help; need some guidance as a collector.

 

I am trying to learn more about: a) the design shown in this recently acquired tsuba; and b) approximate timeframe. 

 

I am familiar with some kebori designs, but this seems like a more distinct or naive carving. 

 

The symbolism represents the human ability to overcome challenges. 

 

Thanks, everyone.

Maybe the design is a rather stylised Nami no Chidori……waves and plovers…..a very popular subject?

For example……

Thank you, Colin. Appreciate the confirmation and the link.

 

In my original post, instead of the wording of 'design', I should have placed more emphasis on the 'carving' style. I have only seen this almost amateur carving on a very, very early tsuba and was wondering if there was a school that was known for this or term and an approximate timeframe.

 

Of course, and more probable, I could be completely off and it is not noteworthy or perhaps a tribute piece from the Edo period.

Never saw this before. It looks like a modern amateurs work.
Do I see correctly the front is flat and the back hollowed?

 

Best,
Florian
