Cheers to Andrew for flagging up an auction that's going to get lovers of space age motors drooling – the RM Auctions motoring sale at Villa d'Este event on the shores of Lake Como in Italy.
The lots range from classic cars to legendary concept cars of the 1960s and 1970s, which are the property of the Bertone museum and the items we are flagging up. Above, you'll find the 1970 Lancia Stratos HF 'Zero' and over the page, you'll find a 1974 Lamborghini Bravo, a 1980s Lamborghini Athon and a 1967 Lamborghini Marzal – the last of those apparently driven by Prince Rainier and Princess Grace at the start of the 1967 Monaco GP.
Want one? Estimates for the concepts range from 60,000 Euros through to 1.5 million Euros for that Marzal. See more images (and more motors) from the auction, which takes place on 21st May. Compared to those prices, the catalogue is fairly cheap at 70 Euros!
