The barcode to Harley Quinn’s: Villain of the Year #1D is incorrect. It should be 76194136489600181 (I don’t own it and so can’t confirm, but the existing barcode is listed as the barcode for 1T in the same series).
The image to the BACK cover of 1D appears to be some sort of preliminary artwork (if you look at the barcode on the image, it’s all zeroes).
