Starting Brief 4 Marks and spencers

Steph and I have decided to collaborate on this project as we both wanted to do the brief but didnt have all the skills to do it on our own. I am very illustration based and want to keep that flowing throughout my briefs. Steph is very good at layout and idea generation.
We have come up with an idea of "wartime".
The brief is too package the perfect picnic, they suggest doing an event like valentines day, Spanish Picnic, etc but we wanted to do something different.

Marks and Spencer have been around for a long time, always providing food throughout the war. I found the paragraphs below very interesting and I have no idea about the history.

 

We want to create a picnic that make people remember what M&S went through to help out in the war. 

My job will be to draw images from wartime, packaging and manuals.

I do not have much knowledge about this at all so I need to do a lot of research and get images of products that I can draw.
