Single Record Sleeves

Here's a nice site showing some tasty examples of the now, nearly forgotten art of designing eye catching single sleeves. It's broken down into catagories for ease of searching with an A to Z of labels as well as general genres like stars, patterns and two colour prints. Above: are two (slightly changed) examples of pleasing on the eye patterns that were designed. These show that simplicity often produces the best results.
