It's similar to 'Professor Sargent', but the flower looks pinker and 'cuter'. It looks more like Nuccio's 'Jingle Bells' (which is still in commerce via Nuccio's Nursery, but they don't supply a photo). There's a photo at the ACCS web site—I can't link to it directly, but you can search by name.

Or it could just be an old anemone-form camellia, of which there have been many. 'Rose Anemone' is a name I've seen used (or misused?) to name a similar-looking flower.
Here's a photo of a camellia growing in my neighborhood that looks a lot like yours:
I loved seeing your camellia banner... what fun!
