Factual error: When Toni and John-Boy make a bet about who will locate Jason first John-Boy is holding a book, and just as they agree to the loser buying a bottle of champagne, this book's author and title are visible on the spine. That book is "A Pocketful of Rye" written by A. J. Cronin, and published in 1969, though this episode takes place in 1945. (00:30:35)
Factual error: When John Curtis walks out to the porch he's carrying a storybook, which John-Boy reads to him, and the year is late 1945 or early 1946. This over-sized Golden book is Richard Scarry's "Best Mother Goose Ever," and at its earliest it was published in 1970 with Scarry's illustrations of "Three Little Kittens" on the cover, and "Jack Be Nimble" on the back cover.

Factual error: After Cindy admits that she needs to know why she was put up for adoption, when it cuts to a clip of Washington DC with the Washington Monument and Jefferson Memorial in the background, we also see vehicles not appropriate for 1945. (00:14:45)
Factual error: After the shot of Erin and Paul driving to his home, which is about half an hour up the road, when it cuts to the exterior shot of the Assayer's office building, all the vehicles parked outside are from decades later. (00:32:10)
