Magazines, Newspaper & Paper (City Centre NR2)

Hi everyone, I’m looking for magazines for collage, art projects and workshops with the community. Good quality colourful magazines such as National Geographic are particularly good but anything with photos or interesting patterns, or old magazines and newspapers, or even books with photos in it would also work, also any coloured or plain paper or card that you have lying around could be good. I live in Blofield but work in Norwich City Centre so I can pick up from locations in Norwich after work or at the weekend. I can potentially travel further afield to collect at the weekend. Thank you in advance :)
