NOS vintage child's tube socks 3 pairs

Description

These socks came from the estate of a man who sold at a local flea market until the late 1980s when he packed everything away until recently.  This listing is for a 3 pack of child's tube socks in various colors.  They are not sized but they measure about 10.5 inches long.  The fiber content is unknown.
I will choose the color randomly but if the buyer sees a color they prefer I will send it if available.
The socks are in good vintage condition.  They have been stored a long time and have a bit of a closet smell.  It's not bad and will go away with first wash.
This listing is for a 3-pack of socks.  I have a number of these packages available.
