A Ministry of Magic owl recruitment poster

The Secret Messaging Service (SMS) was an owl-based communication system that the Ministry of Magic was planning to set up in the late 1990s.

The Ministry needed the best owls to establish this service, so it distributed notices asking for people who had Grade 1 owls to attend a recruitment meeting at Woodside Arboretum.[1]

Woodside Arboretum has almost nothing known about it except it is in the British Isles.

The notice consists of a possibly moving black-and-white picture and a picture of an owl on a brick wall. In the bottom right is a watermark from the Ministry of Magic in the form of an M.
