Die cutting of the cover image or inserts is probably the most common technique employed to create gimmick covers. It's probably also in most cases the cheapest.

There are thousands of die cut covers. Here are a few of the more popular and best known releases.

Tarkus promo box and obis released to accompany the first K2 24 bit release of the first five ELP albums.

The artwork is darker than the album cover. It came with 6 promo obis, 2 for Trilogy.

Some of the images shown here include all but one of the Tarkus Mini LP releases spanning 1994 - 2008

In late 2008 Caroline Records in the USA released a number of albums by the following artists: UFO, Jethro Tull, Quicksilver Messenger, Brian Eno, Roxy Music, The Raspberries, Kate Bush, Blondie, The Band, Red Hot Chili Peppers and Van Der Graaf Generator (full list below).

Unlike the suspect Universal releases these are 100% Japanese. The only difference between these and the Japanese (apart from being as much as 50% cheaper) is a sticker on the bar code of the obi.

As at March 2009 most of these are still available at Amazon.
