Gelukwens NVB aan de Indonesische vrouwenbond
Congratulation from Dutch Women's Movement to the Indonesian women's league
De Waarheid, 14 Aug 1953, p. 3: headline and one-line introduction only, stating that the NVB executive sent a letter to Gerwis; the letter text itself is not in this item (it appears in the companion item 'Dierbare zusters'). Evidence of NVB-Gerwis contact.
