Prescription ray ban sunglasses found 60th Grateful Dead (haight ashbury)

Beautiful brown sunglasses. Very heavy prescription. Lost and found was closed by the time everyone was cleared out. Was talking with friends at the end of the show and on our way out stumbled upon these glasses. Figured I would post it here so that hopefully the owner can find them. I’m sure they are very expensive! Let me know what kind of case it was left in and that will tell me that you are the real owner of them. Please call my cell phone provided, email will take longer for me to see.
