Set of 6 vintage 1960 National Dairy Council Milk posters GVC

Description

This is a great set of vintage dairy educational posters.  They are unframed and appear to be unused.  They come from a local estate and appear to be in their original bag.  The only signs of aging I see is some slight darkening along the edges and a bit of foxing along a couple of edges.  One of them (the delivering milk) is a bit darker than the others.
The posters measure 14 by 18 inches.  They have a copyright date of 1950 and this set is from 1960.  They were put out by the National Dairy Council.
The posters are:
Delivering Milk to the Home
Bottling Pasteurized Milk
Taking Milk to the City
Milking Time on the Farm
Cows Grazing in Pasture
Enjoying Milk Every Meal
