In order for me to properly assess what you have I will need to see images of the front, back (do not remove from frame) and a clear, in-focus close-up of the signature.
If you had already attached images to your initial posting, they are not showing for me here on my end.
Please send the photos at your convenience. There is not an extra charge to provide more pictures here.
An original still life painting by Austrian painter Anna Sattler-SeigerSchmidt (1873 - 1962) can carry an auction estimate of $1000 - $2000 on today's market. The suggested insurance or replacement value is $3000.
