The card "1970 Dodge Challenger Hemi" was blatantly stolen from the first page of Google results. I thought it was simply a difference in editing style between the car and the dog photos, although it was fishy, but as soon as I saw the cellphone baby photos it was pretty clear. If you search the card's title it pops right up in the second row.
I don't know if this one is known already or not since its an older set, but at least one card from "A Trip Around the World" is stolen straight from Google as well. Though honestly, considering the subject more of the photos were probably stolen too.
