I bought Larry Williams and Johnny Watson's "a quitter never wins" years ago, always thought it was a boot of the promo (can't remember where I got it) - no red "A" on either side -  it looks just like the example of the promo on discogs, but the one on 45cat is slightly different - main difference being artists names in UPPER CASE not in Mixed Case.

Boot?

Boot ... Vinyl and massive 5 turn 17mm run-out ... and very poor typeface reproduction especially the "Not for Sale" and "Radio Station Copy" parts  ...  

Real one styrene with much smaller 9mm run-out and nice crisp printing.
