Rules of Civility by Amor Towles
"On the night of October 4th, 1966, Val and I, both in late middle age, attended the opening of Many Are Called at the Museum of Modern Art--the first exhibit of the portraits taken by Walker Evans in the late 1930s on the New York City subways with a hidden camera."
This book takes place in the 1930s, and this is from the Preface. But even though there is a frame around the story, they introduce the time of the actual story right away. I'm not always crazy about a frame--they frequently are superfluous--but I'll reserve judgment.
