I am looking for very high resolution scans of vintage magazine and newspaper covers that represent historical events for a project I am working on.
Essentially looking to print various influential magazine and newspaper covers with historical significance for display in my home.
Is there a time frame or specific historical events you are looking for? This can play some role in determining the useful sources.
Your best bet is probably to buy used copies on the secondary market or see if the magazine publisher themselves offers reprints. Otherwise, anyone selling or posting high-resolution images of the covers is probably breaking copyright and will be receiving a cease & desist from the company lawyers.
