The earliest commercially practical color photography

The first black and white photos date to the 1820s and the first color one to 1842, but color photography wasn't practical as other than a laboratory exercise until the Lumière brothers patented a strange Autochrome technique in 1907.  A glass plate had various colored starch granules applied; the granules acted as color filters allowing actual practical color photography - as the 1917 Nieuport 23 fighter shows.

It's surprising what we have from this period, for example Mark Twain from 1907:

It's interesting just how old some still common technology is.  I posted years ago about Thomas Edison's recording of Brahms himself playing one of his compositions.  The recording comes not on wax cylinder but via Youtube, just as the photos above are on your computer screen rather than printed on paper.  But they are both still recordings and photos, from over a century ago.

Not to mention the first four engine strategic bomber from way back in 1913.
