Nostalgia, graphic design, and just plain weirdness.
Several years ago I helped my friend Matthew Glass share his enormous LP cover collection on a blog he called LP Cover Lover (the tumblr is right here). So it was great to see this interview with him about his collection at Dust & Grooves.
Matthew nails it exactly right when he talks about his sweet spot between nostalgia for the music, graphic design, and just plain weirdness in his collection. Anyone with an interest in any of the above will love his site.
