This is a nice color variant of this classic New York hair bottle, earlier than most. It's pretty crude and fatter than usual, with an applied double collar top. Paneled on 3 sides with beveled corners.
Embossed: MRS. S. A. ALLEN'S // WORLDS HAIR / RESTORER // NEW YORK
Height: 7 3/8"
Color: deep smokey yellow amber, a lighter shade of "old yellow amber" - see pics below for the bottle on the left, shown against another example.
Condition: near mint - no harm 1/4" open bubble underneath on the base, spotty trace wear, but pretty clean and perfect structurally with no chips, dings, cracks, etc.
