A real one off here. Yes it's a 'pay copy' of Eagle annual #5. That is, it's a copy of the annual marked up with who was paid (and how much they were paid) for each page of the annual. I've seen copies of comics that were 'pay copies' but this was the first time I'd seen an annual.
Anyway, for posterity, here are some images from the annual. Sometimes the writer/artist is credited and sometimes it's their agent.
All images are c/o Gray Newell [with thanks to Norman Boyd for reminding me].
