Update: Following the item's absence from the public version of Prop Store's catalogue, we can confirm that the Proton Pack, along with several other items from Ghostbusters: Answer The Call that were due to be sold have been withdrawn from next month's auction.
Over the past few years, auction house Prop Store has provided fans with rare opportunities to get up close to screen-used or production material from the various Ghostbusters films, and their upcoming Entertainment Memorabilia Live Auction will see one of the screen-used Proton Packs from 2016's Ghostbusters: Answer the Call go under the hammer.
This prop is of particular interest, as it features one of the lighting elements added to the thrower to create the glow of the proton stream as its being fired.
Details on the listing will go public on the 12th of October, and the auction itself is scheduled to take place from the 9th to the 11th of November.
There's currently no indication yet if Prop Store will hold a public exhibition of the props due to the current pandemic. We will update this story as soon as we receive further information.
