>Finally if examine the advert carefully you'll notice the thing does not have a power cord. No where is anything plugged into any sort of electrical socket without that power it wouldn't work.
I won't argue against the other evidence Launderess states for this ad being a fake. But...for future questionable ads, no power cord may not necessarily alone mean the ad is fake. It could be just an effort to make things look neater. I think I've seen audio promotional photos that have no cables, presumably to keep things tidy, or else it just wasn't worth the trouble hooking power and signal connections up for a photo shoot.
Back to this ad... I don't know Philco history that well, but from what I know, they wouldn't be making this sort of product. More likely to advertise a Philco radio for every room.
