Sideways is o.k. if it's bottom side down as below. Personally I rather like floating guitars and would not object at all if a guitar like yours floated through an open window in my home one day - however if it was top side down I'd probably just ignore it, because generally speaking, only counterfeit guitars float like that.
Re: the sticker on the op's guitar, bogus looking stickers like that usually have one intent: to cover up what is beneath them, or if the guitar lacks a serial number, the sticker provides one - not one I'd trust though.
