This blank contains a small piece of a beam from Independence Hall.
The original structure of Independence Hall remained intact until 1897, when renovations became necessary. At that time some of the original oak and cedar beams were replaced. The removed beams were stored for preservation by several private collectors. To celebrate the Bicentennial in 1976, Burnes of Boston offered a limited number of chips cut from the original cedar beams of Independence Hall. Each chip was numbered and presented in a beautiful case. This is the source of the wood embedded in your blank.
Thesewere cast in epoxy resin.
Please use a squaring jig with a sander to square up your label cast cast blanks, a barrel trimmer is not recommended, as it can damage the label.
