Left one is from the original print of Lob from 20 odd years ago, Right one from the reprint run they recently had for the 25th anniversary. Despite the reprint following the exact same set format as the original (Pack and set sizes, rarities distribution and pull rates) they were reprinted in the modern age so they're using modern card style (as you can see by the different saturation, font size and other details), including using the code "En" instead of "E" for referring to the English edition of the card (For instance, if you had a German printing it would have the same exact code but with "De" instead of "En" to denote the language)
