Anyone seen one of these before? Currently for sale on Ebay, it's one I've never seen before and have no idea what machine would have dispensed such a card. It appears to be of standard Argyle size, as used in many machines in the first half of the 20th century, such as A - J, Palmist, Future Husband/Wife, Green Ray, Mysterious Hand etc.
I can't think of a Love Test type machine that dispensed cards.
I have a set of 10 different cards similar to this card (which I bought). The texts on the back do not include the text on this card. The card is illustrated below and, as you see, states 'Sole Makers & Patentees A.W. Patents, Southport'. Do not have any idea what the machine looked like though.
