From the Design Observer:
I can’t think of any other design or visual arts publication quite like Signal in form and content. “Journal” is exactly the right word here because Signal, published by PM Press in Oakland, California, is half way between a magazine and a book in appearance and tone. Its dinky size, combined with astutely pitched, matt-laminated cover designs, make it immediately intriguing and attractive. The page design is poised between scholarly seriousness and newsstand techniques of appeal. Signal is generously illustrated and would be rewarding merely to browse, but everything about it says: read this (because it will be a pleasure).
