I sent my "Bedknobs and Broomsticks" Blu Ray Cover to Ms. Lansbury to sign.

In my opinion this is considered a quick response rather than months. lol.
I sent her a S.A.S.E with the cover (and a card board piece so that the USPS didn't ruin it). However, somehow, they still managed to ruin it slightly. The corner of the cover is a bit bent. Could be worse though.... right?
She just signed her name... I got a few other covers addressed to me (from Bob Newhart, Sam Elliott & Katharine Ross). Two Covers just signed a name (Angela Lansbury & Christopher Plummer (Sound of Music) ) .

(When i send a cover to anyone, i make a copy of it first on photo paper, that way I still have something in case i lose my original. I lost my Toy Story 3 cover to Tom Hanks back in 2018...and my Back to the Future cover to Christopher Lloyd (2019).
