Vintage souvenir ticket of US Capitol tour with souvenir pin!

Not exactly sure of the age, but likely in late 50s/early 60s.Ticket in average condition given age. Edges are pretty crisp. No smudges. But various bends in the ticket.

PLEASE NOTE that the souvenir pin goes through the ticket as you can see on the image of the back of the ticket. So best to stay together and there will be holes if you remove the pin.
