Thanks for the clarification and the interesting history about MM; I had forgotten about that marriage. Of course you posted the photo as Norma Jeane, to see if anyone recognized her hehe - I haven’t seen very many photos of her before she was famous, but did recognize her immediately.
Thank you for the link to the DC-6 ad photo. I hadn't seen that one of her before. It was obviously taken after she left Radioplane and started her modeling career.
