Odd Cover Art

[Eva Elisabeth]

My best guess is the author felt an eye catcher necessary to sell Johnson by linking the customers' attention to undoubtedly the only reason that made him occurring in history books at all - without the assassination I think he would never have become president (as which he accomplished to regularly hit the lowest marks in rankings). Stirring a little speculation certainly was thought to add to attraction. Yellow press does that every day on the covers just to reveal nothing new inside. No doubt unfair towards Johnson. (I think it's difficult to make something interesting out of him at all, moreover without the assassination and for kids - it would probably have been nicer to just let him RIP.)

And unfortunately anything bang bang attracts at least many little boys.

And please don't tell me US elementary kids don't get to watch a lot of this:

... or such as the brutal Grimms' tales.
Is that all more appropriate? And how would you sell Johnson (without the assassination)?
