These adorable girls were drawn by Ulla Pihl.
p.s. I tried to find some information on OTA but couldn't. I don't know if it was a cold cereal, or a hot one, like oatmeal.In some of the scans, you can see the thick cardboard that the dolls were printed on.
p.s.s. Blog Friend Jona sent a link to the maker of OTA, which turns out to be the same company that makes oatmeal in the US. I have a box in my cupboard right now. Thanks so much, Jona!
