GCHQ has proclaimed a souvenir be awarded for this special, Once in a Lifetime day of Tuesday, 2/22/2022 (then again, isn't every day a 'Once in a Lifetime' day?)
But they also decided to make it a bit more difficult, in that one must gain TWO smileys to earn it.
Well, a short walk by attendee's of the nearby The LAST 2:22 of 2/22/2022 Anywhere on Earth* event will take care of that quite nicely.
