Hi Juliana,

Thank you for contacting Mearto with your appraisal inquiry.
The markings don't correspond to any Danish or Scandinavian furniture-maker databases I've got access to, which only means I'm not able to make an attribution or identify the maker, but this is a great table regardless...it combines function and form really well.
Based on the photos and information provided, and subject to examination, this is:

A vintage Danish Midcentury Modern teakwood oval extending dining table
circa 1960-80
The oval divided top housing an incorporated extension leaf, raised on trestle legs joined by an H-stretcher. Stamped underneath the top " AM 88 / Made in Denmark" and "D00000185."
29 inches high, 68 inches long (98 inches long extended), 42 inches wide
CONDITION: This table appears to be in good condition; value assumes no chips, break, repairs or losses.
PROVENANCE: Purchased in 1984 from Shop Skandinavia in San Antonio, Texas
$1,200-1,800*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
