Give a retirement gift caricature - leaving a place of employment after a number of years is a major event in someone's life.
To be acknowledged by your boss, colleagues or staff can have a profound effect on a person's memory of their time spent with you. Having been present at a lot of retirement functions I can say that of all the gifts that have the greatest impact are those that are highly personalised, and very few can match a caricature in this regard. Why is a digital caricature such a good retirement gift? Simply because it can encapsulate the person, their personality and their history at the workplace.
This does not have to be complex - just a few elements, a sign or logo somewhere is all that is required. Of course including their future plans is also possible!
It's as easy as 1/ INFORM, 2/ SEND PHOTO and 3/ ORDER.
