Thank you for submitting your item for appraisal. This appears to be a second half 20th century, heavy slab-form redwood or pine top on burl and root support table. Such tables were very popular in the 1960s and 1970s and are still being produced. Famous designers like Nakashima or Auböck designed similar, but the table in your possession is unfortunately anonymous and can not be attributed to an artist or artisan or designer. The estimate is based on auction results.
