Search "graphic design" in Google Arts & Culture and a wealth of links to archives will turn up! Once you make a selection, you'll also see suggestions at the bottom of other work by the same designer, similar images, and work done in the same era.
In a time when histories are being removed, hidden, and made illegal to teach in schools, your support for The People’s Graphic Design Archive is more important than ever. This is your archive and survives on your support.
