Signed Lithograph of Korean War Veterans Memorial

this is a lithograph that depicts the korean war veterans memorial .. It is in original frame. I spoke to the architect named William lecky who is one of the names on the litho. He said that only the first 200 had original signatures. The names on the bottom are William cooper and William lecky of cooper lecky architects. Frank gaylord the sculptor. And at the moment the muralist name escapes me I was told they sold for $450 at the dedication of the memorial... ide like to know if i need to get this in sured or if its relatively insignificant outside of intrinsic value

Good
