Another new kind of Weekly Penguin entry; ice bags. Yep, I have several of these and I tend to find a new one each summer. No surprise there, really, since a penguin is the best possible logo/mascot for this kind thing. This one is appropriately labeled as 'Keep Cool'.

By the way, sorry for not showing full picture of this one. This bag has a glossy and glittering silver surface was painful to photograph and even more troublesome to scan. What you see here is a cropped view with heavy post-processing, but in this case the mascot is all that counts, isn't it?
