Gerstenberg Headstone

Gerstenberg Headstone, originally uploaded by ChicagoSage.

This was taken at the Graceland Cemetery in Chicago. I haven't been able to find confirmation of this on the internets, but I am guessing this is the tombstone of Alice Gerstenberg, the Chicago playwright involved in the "Little Theatre" movement.

If anyone knows for certain, please leave a comment.

UPDATE:
According to someone in the comments, this is actually the headstone for Adolph Gerstenberg, Alice's uncle and a member of the Chicago Board of Trade for over 50 years. To whomever left the comment, thank you!
