Most of the works drivers of the 1950s were amateurs, paid little or nothing, reimbursed their expenses and given bonuses for winning (although there were certainly exceptions, such as the Grand Prix drivers who were brought in for some events). Then in 1960 came arguably the first rallying superstar (and one of the first to be paid to rally full-time), Sweden's Erik Carlsson, driving for Saab.
In Germany, the Herkomer Trophy was first held in 1905, and again in 1906. This challenging five-day event attracted over 100 entrants to tackle its 1,000 km (620 mi) road section, a hillclimb and a speed trial, but sadly it was marred by poor organisation and confusing regulations. One participant had been Prince Henry of Austria, who was inspired to do better, so he enlisted the aid of the Imperial Automobile Club of Germany to create the first Prinz Heinrich Fahrt (Prince Henry Trial) in 1908. Another trial was held in 1910. These were very successful, attracting top drivers and works cars from major teams – several manufacturers added "Prince Henry" models to their ranges. The first Alpine Trial was held in 1909, in Austria; by 1914, this was the toughest event of its kind, producing a star performance from Britain's James Radley in his Rolls-Royce Alpine Eagle.
Rising investor confidence also indicates a rally, and it is perhaps more powerful than any economic indicator because when investors believe something is going to happen (a rally, for example), they tend to take action (purchasing shares in order to profit from expected price increases) that actually turn expectations into reality. Although it is an objective concept, investor sentiment shows through in mathematical measurements such as the put/call ratio, the advance/decline line, IPO activity, and the amount of outstanding margin debt.
