You may remember the Blackhawks celebratory blog post a couple weeks back. Since then, button collector Joel Carter ordered a 1968 Chicago Blackhawks 3.5-inch button from eBay.
What happened next was pretty interesting. Differences in the mid-century logo and modern Blackhawks became evident, as pictured above. Notice detail in the feathers. The color scheme. And interestingly, one logo is frowning, and the other is smiling!
