The group "Otis Day & The Knights" was originally created for the 1978 smash-hit comedy "Animal House". They can be scene in two key sequences, especially when the "college preppies" end up at the Dexter Lake Club to see Otis Day and the Knights perform, not knowing it's an all African-American bar. This is the sequence where Otis and company sing "Shama Lama Ding Dong". These are the five actual hero screen worn sparkling dark blue tuxedo coats with black trim, single button, single breasted jackets that Otis and his Knights wear in this sequence. One of the jackets has extra trim on the cuffs. This is Otis Day's (aka DeWayne Jessie) jacket. All the others have name, size and date tags inside the jacket pocket (with one blank, but with "Eduardo's Tuxedo Rental" tag inside). From the "action" sequence, one of the group's jackets has a small tear under the arm, and another has the front button missing (but it is in the front pocket to be re-sewn). You get all five matching "Otis Day and the Knights" jackets in all! A panel of industry experts not affiliated with Premiere Props in the movie & TV memorabilia business has authenticated this item. This item now includes three levels of security: 1) DNA laced invisible ink – a 9-digit code laced with DNA ink is placed on an appropriate place of the prop/costume and can be only viewed using a high-frequency UV light. The chances of replicating the specific DNA sequence which is unique to MPDNA is 1 in 33 trillion. This DNA sequence is so secure it is admissible in a court of law.?? 2) Archival Microchip Encrypted Tag - a patented, acid-free, 1"x 3" tag with an encrypted microchip is placed onto the Certificate of Authenticity. The microchip contained within the tag contains all of the pertinent information about the prop or costume. The tag is tamper proof and the microchip is encrypted, making it impossible to duplicate.? 3) The certificate also has the 9-digit DNA invisible ink mark which must match the 9-digit invisible ink mark on the prop. This will ensure that it is a genuine prop issued by Premiere Props and authenticated by MPDNA.
