TIMONIUM, MD. — Of course, right?! On the week that the Greta Gerwig-directed Barbie movie earned more than $1 billion in worldwide box office sales, the mania would be mirrored in auction halls across the United States. For Richard Opfer Auctioneering on August 10, it boosted a lot comprising a 12-inch-long vinyl case filled with assorted Barbie clothing and accessories (some of which may or may not be all Barbie) to top lot status, selling for $510, including buyer’s premium. More from this 400-lot sale to come in a later review.
