• In some versions of this card's artwork, a Monster Card is featured with the artwork of "House of Adhesive Tape".
    • Also, in the aforementioned artwork, the card has the design of an old OCG Monster Card instead of a Trap Card.
    • Moreover, the aforementioned artwork has been edited in the TCG, removing the name of the swept card.
    • Considering the duster is attempting to destroy the monster in the alternate artwork, this implies that the monster is being treated as a Spell/Trap Card.
  • This card has a counterpart: "Raigeki"
  • This card's effect is one of the four Forbidden cards that has its effect featured in "Fuh-Rin-Ka-Zan".
  • This card, along with "Yata-Garasu" are the only cards that have been Forbidden since October 2004. It has however since been unbanned in January 2015 in the OCG, while it remains Forbidden in the TCG.
  • This card was one of the first cards to be Forbidden, in October 2004. It did not come off of the list until January 2015, ten years and three months later. As such, it has spent more time on the Forbidden list than any other card in the OCG before becoming Limited once more.
    • In the TCG, this record is instead held by "Raigeki", which was also Forbidden in October 2004, and remained so until October 2014 in the TCG, ten years later. "Harpie's Feather Duster" remains Forbidden in the TCG.
    • When counting both the TCG and OCG, "Harpie's Feather Duster" holds the overall record, as it was Forbidden for three months longer than "Raigeki". Ironically, despite this, its arguably inferior counterpart, Heavy Storm, still remains Forbidden in the OCG.
  • Since this card is only played by Mai Valentine in the anime and its effect contains a new pair of wings a face-up "Harpie Lady" gets, it can be speculated that the actual anime effect requires a face-up "Harpie Lady" on the field.
    • Though in her Battle City duel against Yami Marik, she played this card without controlling a face up “Harpie Lady”, so it’s likely that this card is just extremely rare (when Seeker was looking up the profiles of Battle City participants, this card is listed as her rarest).
    • Additionally, although at least one Cyber Harpie Lady is present on the field in the other two instances that it was played, none of them gains extra wings when this card's effect was applied.
    • This effect of giving “Harpie Lady” an extra pair of wings was probably a left-over element from the manga.
