From England-Michael Robbins was on a show you may have seen called The Great Big Tiny Design Challenge!
This is his version of a study on Mushrooms.
He made the shelf and it has several books and a chart on mushrooms. Inside the shelf on top is an ink well, a potted mushroom, and six books, the second shelf has the mushroom chart, a dome with five mushrooms, several labels, a pot with three mushrooms, and a rolled parchment, the bottom shelf has a one eyed bottle with cork, a roll of string, and a potted mushroom sitting on a book and a large potted red topped mushroom.
This is just the best display ever for anyone interested in mushrooms.
The shelf is 12 1/2" tall x 2 1/2" wide x 1 1/2" deep.
