My fading memory is failing me and I can’t recall the book it is from. It was full colour. A Shaman was summoning some sort of city setting spirit in, what I recall, was a back alley. Garbage cans and other stuff was coming together into the form.

Thanks in advance.

The Cover of MITS, maybe?

BINGO!

Thanks, all my old books are packed away and I couldn’t recall the exact book and my Interweb searches weren’t getting me anywhere. Thanks for the prompt, helpful reply.

Glad to see I've been getting my descriptions right.
