It was custom made for me maybe 25 years ago. There was a guy at the Orange County Outdoor Marketplace selling unfinished oak furniture. I described what it wanted and we agreed on a price...$300. Then I met him at his workshop and brought a few chips for sizing. When I came back to pick it up I blown away by the job he did. Each chip sits in a circular recess with a backward tilt plus sliding glass doors with a lock. Gave him a $50 tip. I put a UV film on the glass. It's my main piece of "artwork."
