WPN founder John Watson started up WWAV with Albert and decided to support the Princess Alice hospice where his friend passed away in the spring by contributing creative work for its Christmas appeal.
Watson said: "Chris made what I think was a massive contribution to make DM a more respectable medium and to that extent I think we all owe him something of a debt."
The hospice's Christmas appeal has previously focused on inviting warm donors to dedicate a light on the hospice building. This year it has been repositioned to attract cold donors and put more focus on donations.
WPN has created direct mail, posters and leaflets as part of the campaign.
