Was it the Eagle that used to have a page of adverts for very strange objects? The one I always remember was for the 'Seebackroscope' which was a device to enable you to see behind you whilst looking forwards, and it cost about 1s/9d plus 4d P&P. I plagued my dad for one, but he just said it would be rubbish and wouldn't stump up that huge (by those days' standards) amount of money. I thought it would be very useful for when I was doing my paper round. :0)
