1964 Subscription Form
This house ad with subscription form comes from Girls' Romances #105 (December 1964). If purchased by subscription, readers would get a two cent discount -- not too shabby!
Lucky was the girl who was able to subscribe to all seven titles of DC romance comics for two years. At ten cents a copy (in the United States), with 100 issues -- purchasing them all would have been $10 in 1964 -- just about $70 today.
Considering Seventeen magazine was fifty cents per issue in 1964 (about $3.50 per issue today), DC romance comics were a steal!
