Dear Rich Staff to take a picture of a lovely dahlia blooming not far from Dear Rich headquarters. Now, if only we had time to stop and smell it.
Right, you had a question(s). (1) We consider all 11 of your greeting card images to be published works because you have distributed the cards to the public by sale or with the intent to transfer ownership. (If you had only displayed the cards or given them to a select group of people with restrictions, they would be considered "unpublished.") (2) You're on the right track by adding "approx" when providing date of publication. If you’re not sure, state your best guess -- for example, “October 14, 2011 (approx.).” (3) No need for two registrations. As the Copyright Office explains, you should be able to manage with one registration for a group of published photos.
