thumbnail_B0053VMNY2_EBOK_portrait.jpg (The Oxford American Dictionary)
pixel dimensions: 216 x 276
print size: 3 x 3.833 inches
resolution: 72 x 72 dpi
color space: grayscale
The Oxford American Dictionary does not display as tall as the other covers, the thumbnail baseline is the bottom edge.
Not all displayed covers have a thumbnail.
The cover for "A Christmas Carol" was generated by the Kindle itself when the book was placed in documents over USB storage. (I guess books didn't come with jpeg thumbnails back in 1843.)
