I especially like entry #31 and #28. Could we see the tree/child image with just the words "North Country Children's Museum" minus the NCCM. Then see a second version with the tree/child image and just "NCCM" not the full name written out.
New entries with your suggestions. #61 both lines have the same size of letters. #62, #63 and #64 Different solutions in which Children's museum is larger.
