Lead Nipple Shields: correspondence in the British Medical Journal

Entry: 

Nipple shields, the S.3 exhibit that precedes our toy car.

R. G. Howat and Joan S. Blacksell respond to the government's embargo on the use of lead nipple shields, 22 Oct. 1949. The language used is particularly interesting, and reminiscent of the car's accompanying notes.
