Listing detail - "This is a very rare, lightweight, tan/off-white, plush beaver fur tall top hat. Could date anywhere from 1810-1850. It's of a piece, the base is felt, with a furry, plush surface, the crown has a flat, felted surface. It's about 8 1/2" tall, the brim is about 2 5/8" deep. While an average top hat, either a flatter beaver or a silk on a card base, might weigh 8-10 ounces, this is about 4 ounces.
This is the only one of these, in any color, that we have seen in 35 years of collecting."
A rare look at the type of shapes in existence at the turn of the nineteenth century.
Sands Films in London, where I trained after leaving college, make their hats just like this, I remember seeing them for the first time and wondering if it was an exaggerated interpretation.
