From the Hello Dolly! collection of Broadway favorite Carolee Carmello:

An iconic red feather headpiece that Carmello wore in her performance as Dolly Levi in the national tour of Hello, Dolly! A photo of her wearing the headpiece (perhaps It could be framed with the headpiece in a shadow box and add the photo as part of the display). Plus, a windowcard from the Hello Dolly! national tour thats been autographed by Carmello.
