Together again - printed side-by-side, these blocks of four and eight twopenny blues, exceptionally brilliant in colour, used to belong to separate collections. Due to a paper shortage the twopenny blue did not appear until 7 May 1840, two days later than the world's first postage stamp, the penny black. Priced at pounds 220,000 at Spink's exhibition "The Many Faces of Spink", 5 King Street, St James's, London SW1, until 12 December (0171-930 7888).

Difficult to wrap for Christmas but with an all-year-round festive look - this colourful high-Gothic style horse-drawn Reading wagon of about 1900 is estimated at pounds 8,000-pounds 10,000 in Brooks of Olympia's sale of collectors' cars and motorcycles this Thursday (6pm, 0171-228 8000). Romanies who could afford a "van" by Wright, Burton, or an exceptionally roomy one such as this, by the foremost maker, Dunton of Reading, had it made. It would have originally cost up to pounds 200, the price of a small house.

Flightless but speedy: studio potter Jola Spytkowska makes fantasy creatures using junk as moulds. This 12-inch tall Roadrunner, with undercarriage inspired by the whirring legs of her frenetic bantams, is fired by the immensely tricky Raku process in which kiln-hot ceramics are dunked into sawdust - hence the crackled glaze and carbonised unglazed bits. Price pounds 500. She is among 13 members of the Balls Pond Studio of contemporary ceramicists at 8b Culford Mews, Islington, London N1, who will be showing their work at open weekends, this weekend and 13-14 December (11am-6pm, information 0171-254 4037).
