I dont know if it is antique . I see no name anywhere.
The 2 drawers inside are dove-tailed
The marble top is a king of swirly orangey color
The 2 front cabinet doors has a key to open them
It has only 2 very small age related marks real close to the floor that you wouldn't notice unless it was pointed out to you
Burled wood------ BUT WHAT KIND OF WOOD???
Please help me better identify what I have here

As Always,
