My brother-in-law, Dr. Thep Himathongkam is a camera collector as well as a very good photographer. Here you can see him just about to purchase a working 1930 Leica M1, the historic model that started 35mm still photography. Doubtlessly an M1 is quite a prized collector's item.
On the upper right-hand corner of the picture you'll see a photo of the King of Thailand, himself a very good photographer.
