"I don't think that Abraham Lincoln was saying much of anything on June 16, 1964," an AAA World magazine website commenter points out after reading a July/August feature that mentions Lincoln's "1964 speech" in Philadelphia. AAA's Facebook page overseer writes: "Maybe it was Lincoln's ghost who spoke in 1964! " AAA World editors humorously address the typo:

Many of you noticed a slight error in our July/August feature, Ghost Fields, where we suggested that President Lincoln delivered a speech in Philadelphia on June 16, 1964. The actual date of the president's speech was June 16, 1864. Of course, everybody knows that Abe was touring with the Beatles in 1964 (photographic evidence below). Needless to say, we're truly embarrassed. We apologize.

Here's the photographic evidence:
