You may recall the post I did a while back on Daily Book Graphics. Well apparently I misidentified several of those images as vintage covers when in fact they were modern works by designer Julian Montague who is part of the Buffalo based design duo Frazer / Montague.
Julian Montague has collected a wealth of inspirational book covers from the 1950s-80s. These are just a few of the great designs I came across while browsing through his Daily Book Graphics project. You can see the rest of the set on his Flickr, or check out previous posts for more vintage book covers.
