The Leica Family Tree (Leica Stammbaum), that was purchased by the Leica Store Manchester last year, is currently being auctioned off at Christie’s in London:
“A history of the Leica camera comprising 107 of the principal models, showing the history of the marque from pre-production models, the screw-fit Leica series, M-series, R-series, to digital models, from c1923 to 2006, mounted as a family tree by model and date of production, on a custom-built display unit, formerly part of the Leica Sölms factory museum.”
The estimated selling price is listed at GBP 350,000 – GBP 450,000 (USD 456,400 – USD 586,800). The auction will run until 14 September, 2016.
Here is a better/more complete version of the Leica Family Tree – the poster is showing the evolution of Leica cameras from the Ur-Leica in 1913 to the M9-P in 2011 (update: a better resolution can be found here):
