.ON MARCH 10th Kensington Palace launched a picture of Catherine, Princess or queen of Wales celebrating Mommy's Time with her three youngsters. By the following day, after uncovering that it had been revised, 5 photograph firms had pulled account from their cords. Little princess Charlotte's hair, sleeve and dress seemed to have been played with. The Princess of Wales apologised for the improvements, which she says she produced herself, qualifying all of them as the experiment of an amateur photographer. There is no recommendation that they were planned to trick the public.
