How do you make a Christmas tree out of toilet paper? What were the coolest toys under the tree in 1956? These and other burning questions will be answered when the Charles Phoenix Retro Holiday Slide Show comes to the Kirkland Performance Center at 4 p.m. Dec. 27. It’s a laugh-out-loud funny celebration of mid-century American holiday culture that goes beyond Christmas for an overview of all the holidays we hold most dear. Tickets are $20 adults, seniors and youth. For information, visit www.kpcenter.org or call 425-893-9900.
