A penguin squawks “spread the word — the holidays are here” to his friends from an icy glacier. This is the front of the annual Siteman Cancer Center holiday card. A set of 15 cards is $12 and can be purchased at the Barnard Health and Cancer Information Center, located on the first floor of the center for Advanced Medicine. The cards can also be ordered by calling 362-7844. All proceeds will benefit the Siteman Cancer Center.
