Hi All,
Gloria Swanson matte finish gelatin silver double weight 8x10 signed portrait with photographers embossed stamp lower right, dedicated and inscribed in blue fountain pen "To Dominick from Gloria Swanson, "Sunset Boulevard", 1949", which is well before the film was even finished being written. It was finally finished in January 1950 with major re-shoots - the original introduction began in a darkened morgue with Bill Holden's glowing drowned corpse under a sheet talking to a dead little drowned boy under a sheet and it freaked audiences out. At best some thought it was a comedy. It was eventually released several months later in a very altered form with a new intro and ending. I have a copyrighted 1949 production still showing the original unused bedroom ending scene (she looked TOO crazy!) which I will pair with this. What better example of an inscription giving a context - date and time and sometimes location? This pretty much IS "10086 Sunset Boulevard!" Really a two for one, as it is the films title as well ;)
And see below!

Note - the scan is looking a little light to me, at least on my laptop.
