Lots of record companies used to do stuff like that, if I recall, Riverman. I remember buying albums by Bobby Hebb and The Marvellettes that did the same thing. In fact, ironically enough, it seems to me that Arthur Conley's "Sweet Soul Music" album managed to avoid having a picture of him. Jeez, imagine our surprise upon finding out that he did not look like Johnny Tillotson!
Hey,I remember that Marvelettes,Please Mr. Postman album.It had this picture of a mailbox with a spider web on it.No picture of the group anywhere.
Bobby Hebb!Now THATS a good singer who never got his props.His follow up to Sunny,Love Me,sounded exactly like the hit but his next single,Satisfied Mind,is one of my all time favorites lyrically.
Never went anywhere on the charts,tho!
