Hi Kalman, for a long time nothing heared from you. Is it possible to show us a scan of the picture? So we could say more about it, I think. Probably it could be a picture out of an advertisment brochure. If you send a scan, I will have a look in my own brochures.
This appears to be a promotional postcard, it could either appear on its own, or in a brochure or advertisement. It is likely that this piece would have appeared shortly after the launch of the Olympic, and was probably also re-labeled and reused, as most of Olympic's interior was, as the Titanic.
