“Friends” memorabilia and other valuables from the estate of Matthew Perry are being put up for sale at an auction to benefit the charitable foundation established in the actor’s name soon after his death. The auction includes cast-signed scripts from the first and last episodes of “Friends” and artwork owned by Perry will be put up for sale by Heritage Auctions on June 5. It will benefit the Matthew Perry Foundation, which works to destigmatize addiction and aid in recovery from substance abuse. Perry died at age 54 in 2023 from what authorities say was an overdose of ketamine.
