That was a record custom-pressed by RCA Victor for Ponselle, as a fund raiser for the Baltimore Symphony. I checked eBay completed listings, and did not find it, which means it doesn't turn up very often. It's certainly a collector's item, but I'd hesitate to guess the exact value.

Subject: [ARSCLIST] OPEN HOUSE WITH ROSA PONSELLE
I have an LP copy of OPEN HOUSE WITH ROSA PONSELLE.
I'm wondering what it's worth.
Does anybody know?
