Does the Style of Design Die off?

After reading  "To the Point: Interview With Dave Perillo, aka Montygog" , I asked myself  the question "does the design of an era or decade die off?" and looking at Dave Perillo's art I take that as a no. I recently went to Shoprite and found a bag of 50th annaversary Bugles Bag an thought "wow this is awesome." even though I wasn't born during the 60's I could still appreciate the design that was common place. Another way you could say its design is still relevant, because its breaths new life into a age old brand showing its long history with its customers.
