Wooden pedestal bowl

Bought this hand made wooden raised bowl just because I appreciated the skill that a master wood worker put into creating it. It’s not fancy it stands just under 5 inches tall with an opening of 8 inches across. I don’t know what type of wood it is. The bottom is marked in pencil 4- 139 Walt Liebke 12033. There is an attached piece of paper saying from Bob, Christmas 1973 or 74. I don’t collect wood objects, but I thought this is art just in a different medium. Thanks for looking.
