Why not buy that piece of pottery, and once the weather gets warm, take it home and use it in your rock garden or garden area? It will be a unique piece, and can add some color and panache to the area. If it's chipped, you don't have to worry about damaging it further. Also, like the top green planter, you could add some more flowers, colorful rocks, or whatever would work for your garden.
The Roseville Vase below is for sale by gracetimeline on Etsy, so I would advise against putting it in the garden since it's still in great condition. In fact, it still has the original foil label. Let's pretend that you come across a similar one at a second hand store or estate sale though, and it's not in the best condition. Wouldn't it look lovely outside surrounded by tall flowers. If it's chipped in the back on one is likely to be able to tell. It would be a perfect garden decoration, vintage style for outside.
