At the age of 67, Mick Jagger and the Rolling Stones are still going strong - as is Stones memorabilia from their shows and tours.
While the Stones continue to sporadically release discs, most recently a rerelease of Exile on Main St that included 10 newly-finished songs, it is the band's live performances that capture the public's attention.
Mick Jagger appeared at the Grammy Awards in California earlier this month and rumours persist about a possible tour later in the year.
In these times of cheap downloads, touring is often the key to making a good livelihood as a musician, not that the members of the Stones should be facing too much financial hardship.
This is great news for collectors, as memorabilia from shows and tours can make for some excellent investments.
Collectibles from shows during the Stones' Brian Jones era are especially popular with collectors. A rare poster from a performance at Queen's Hall in Leeds in July 1964 sold for £7,800 and a poster for a performance at the Gaumont in Hanley from September 1964 recently achieved £10,200.
Memorabilia from performances beyond the band's 60s heyday are also beginning to become hot property.
For example, a jacket from the band's 1981 tour sold for £216 at a 2006 auction while a 274cm square backdrop used during the 1995 Voodoo Lounge tour, signed by the band, recently realised £4,800.
