Block for block Lexington Avenue seems to have more older buildings than any other north-south Manhattan avenue. This pair at the SE corner of East 39th Street seems to be about 40 years apart. My educated but probably incorrect guess has the corner building from the 1910s and the adjacent building sports the slanted mansard roof and rooftop ironwork emblematic of 1870s and 1880s architecture. They form quite the contrast to the skyscrapers in the background, 622 3rd (Grand Central Plaza) and 600 3rd, which face each other across East 40th. Those buildings date to 1971 and the 1980s, respectively.
