There’s an infamous inappropriate Star Wars trading card of C-3PO. It features the droid with a huge erection and it is the only the second most obscene trading card out there; it didn’t’ even make number one.
Anyways, Card #207 of the fourth series is the said obscene trading card and no one knows exactly how it came about. Legend of course blames the massive golden mishap on a disgruntled artist. The art was later fixed with airbrushing and is actually rarer than the well-endowed trading card of the droid is.
Other inappropriate trading cards are definitely out there. There’s an infamous Fleer f*** face baseball card. Other inappropriate artwork blamed on disgruntled artists are the cover of Disney’s The Little Mermaid video and the notorious Renuzit air freshener can.
It is far from the first time that phallic symbols and inappropriate text has appeared on merchandise.
