These two pictures were included in the online portfolio of Frank Cravotta, the Director of Creative Services for the Buffalo Sabres. They include early sketches and designs of the 'slug' and the 40th anniversary jersey.
The really interesting part about the 'slug' concept is that the Sabres wordmark seems to have been originally planned between the NHL collar logo & the main logo, ala what Nashville did a few years ago with their mustard yellow thirds.
Its embarrassing going to the Arena and seeing 3 different logos hanging from the rafters. Don't try and re-invent the wheel, take a page out of the Habs/ Leafs/ Wings/ Bruins book. If you want a new look do it with the 3rd sweater, don't deface a great logo with a goat head or a slug.
Another reason why Buffalo never gets to sit at the big boy table.
