Sylvia,
You can get some very nice posters from THE FRIENDS OF BREASTFEEDING SOCIETY,
RR#3 Clifford, Ontario, Canada NOG 1MO tel. 519-327-8785. Posters are $1 each
with a minimum charge of $15.
I believe there is a print for sale in the La Leche League Int'l. catalog.
Best Start also has some beautiful posters.
Linda
