Probably made at the beginning of the 20th century.
Collar size.........16 1/2 inches (to fit shirt size 16 inches). Depth 2 inches approx. (this is a deep collar, and you will find it uncomfortable if you are not used to wearing starched collars).
Condition: This collar is over a century old, but has never been worn. It is unsold shop stock from around the 1900s, and is still in good condition, but with some scuffs from storage. It might do for display or costume use, but if you wanted to wear it for ordinary use, it would need to be laundered and re-starched first.
