I highly doubt they had it blank,the group America tried that with their 1976 LP,"Hideaway". Just a picture of the group in front of a winter chalet (fancy word for cabin).
It didn't sell well and that's only part of the reason. The other...by that time they were a bit overexposed and "had" to put out LP's due to contract.
Getting back to Gord's LP,a title-less cover is not a good idea for an artist trying to breakthrough on the pop charts. Especially a country to country cross-over.
Been me. Later!
