Arthur Weasley remembered what Alastor Moody looked like when he was still a whole man. Back before the first war stole an eye, a leg, and part of his nose. Then the second war came and stole his life.
The picture on the Chocolate Frog card came from a time between those two wars, so even now young wizards and witches who collected the cards would only know the visage of the damaged man, would always see him as "Mad-Eye".
Arthur had looked up to the other wizard when they were young. Moody, or Al, as he preferred to be called back at Hogwarts, was two years ahead of Arthur in Gryffindor house. Both of Al's parents were Aurors, three of his grandparents were Aurors, and some of his great-parents were too. Al effortlessly gave off a powerful, commanding presence. He was a true lion, stalking their common room.
Al excelled in classes; it seemed he didn't even have to try in order to get O's on all of the O.W.L.'s he chose to take. Witches flocked to the intelligent, muscled wizard with the shining blonde hair.
The slightly dangerous aura he gave off didn't hurt.
Arthur couldn't believe the chocolate manufacturers waited until after Moody died to give him a card. Arthur considered it a travesty. He should have received one after the first war. Without him on the side of the light, there would have undoubtedly been more tragedies. He revolutionized the Auror department in his time there. He went into retirement a legend.
Arthur didn't want to belittle Moody's important role in the second war, but dammit, if this wasn't something that chafed him. Arthur should be looking at an updated card that included new heroics in the effort to keep Harry Potter alive, not a card that Moody would never know existed.
Arthur's sour mood was broken by the humorous thought of Moody's possible reaction to his box full of complimentary cards arriving in the post. The man would probably hex the delivery owl, blow up the box, give a nonchalant shrug while stating, "Constant vigilance," as the ashes rained down on him.
