Most of these fit the Altoids Tin Book Covers (a bit larger than an ATC, but they could also be cropped for using on ATCs). They will also fit the height of the ATC Sized Faux Book Box (they'd need a bit of trim added to the sides to fill the entire cover).
That larger image with the birds and flowers also fits the Altoids Tin Book Covers, but sized so that the pediment would be above the top of the cover (and you could either omit the extra trailing flowers below the window, or perhaps make a base for your book from a Candlestick Holder or other item).
