Personally, I get too many cards with similar scuff-marks and misprinted barcodes in very predictable areas to call these things “interesting.” For the people who make lemonade out of lemons, more power!
As I’ve said in the past, I don’t consider a 1920’s card that arrives with an orange barcode printed across the front or a hand-made cut-work card where half the picture has been scraped off to be a proud survivor, I consider it to be a damaged card. I am especially sad when vintage, hand-made or truly one-of-a-kind cards arrive having suffered such abuse.
Maybe the solution is for me to take “positive imagination training” or something similar so that I can invent stories for these cards. I would prefer, though, kinder sorting machines.
