These are radios design to look like something from the 1960s or 1970s. Indeed, one of the designs (the yellow one) looks almost identical to the classic Toot-a-Loop radio of the late 1960s. If you want an original of that design, there are a number on eBay right now.
But if you want this one or the other two, they are available from Magpie, offering FM reception, mains or battery power (batteries not included) and a headphone jack.
£30 is the price of each.
