In the days before we were encouraged to have three Weetabix for breakfast – if a family could afford them at all, it was invariably one each apiece – Dinky Toys produced a limited number of their Guy Vans in the breakfast cereal's livery. This one goes into Clevedon Salerooms' March 11 specialist auction at Kenn Road with an estimate of £250-£350 – which sounds pretty good, but could be better. "It was brought in with other items on one of our free valuation days, and the vendor had owned it from new," says auctioneer Toby Pinn. "Of course, if he'd chosen to leave it in its box and play with his other toys when he was little, it would have been worth £1,000 now!"

A few onlookers are expected to fall in love with this sweetie at Charterhouse's auction at Shepton Mallet Showground on Valentine's Day, and bidding could well go up to about £5,000. It's a rare Seeley Honda 750 CB Café Racer, the 23rd of just 300 built between 1975 and 1978, and at 75kg lighter than the standard 750 CB, it can whizz along at 130mph (preferably nowhere near where any of us live). The auction is held in conjunction with the Footman James 1st Great Western Autojumble, and viewing is 10am-4pm on February 13 and 10am on the Sunday.

Again with Valentine's Day in mind, this Victorian 15 carat gold, turquoise and half-pearl set bracelet will go under the hammer at Dreweatts 1759 Bristol's jewellery and silver sale at Apsley Road, Clifton on February 9, teamed up with an Edwardian 18 carat gold, turquoise and diamond five-stone ring. Together they are estimated at £250-£300.

She doesn't look the brightest star in the Edwardian firmament, but the model who posed for these chromo lithographic glamour postcards put out by the London publishers the Birn Brothers will doubtless appeal as much today as she did back in 1905. The postally unused cards plus two others – one of a Christmas angel, the other of what looks suspiciously like a Mucha girl without being identified as one – are offered at Tamlyn and Son's collectors' sale in Bridgwater on February 9 with an estimate of £30-£50.

This vase made in the Pilkington factory near Manchester in 1909 goes into Lawrences of Crewkerne's decorative arts sale in April estimated at £500-£800. It is the work of the company's head of design, Gordon Forsyth, who was greatly influenced by Middle Eastern lustre painters of medieval times and helped push Pilkington and Royal Lancastrian to the forefront of turn-of-the-century art pottery. They were popular back then, but it's fair to say they have never been more prized and admired than they are today.

This is no more than artwork for a Twenties magazine spread on bathing costumes, but it's such a joyful and carefree image that many of us would be delighted to have it on the wall. You will find it on the Somerset experts Gray Modern and Contemporary Art's stand at the Bath Decorative and Antiques Fair on March 5 and 6, as part of a constantly changing stock of work that ranges from modern British artists of the standing of Elisabeth Frink and Frank Auerbach to cutting-edge figures such as Tracy Emin and Andre Butzer and decorative fashion artwork from the inter-war years through to the Sixties.

Antique scrapbooks are intriguing, and a big, packed one at Greenslade Taylor Hunt's sale in Taunton on Thursday is a classic. The vast book was partially filled in Victorian times and then finished at the beginning of the last century, with contents ranging from beautifully painted 19th-century botanical sketches to World War I newspaper cuttings. Reams of fashion prints are included, and the compiler also seemed to have had a particular fondness for Prince Albert, whose portrait appears on page after page. From later times, in contrast, is this 1928 newspaper insert commemorating the Taunton Historical Pageant, complete with Judge Jeffreys, the Lady of the Lake and a whole battalion of Saxons. It's a reminder, when we're inclined to look back on the good old days with rose-coloured specs, that at least we don't have to sit through hours of historical pageants any more. These pages haven't been near one since the Preston Guild of 1972. Or, indeed, ever quite recovered from it.
