Gum (San Francisco)

 
 

A Light Show from San Francisco that I am seeking more details on.

Can you help? If so please contact me via the link below.

Gum lit Quicksilver Messenger Service and Congress of Wonders at The Matrix on September 1st to 3rd 1967.

I do have a handbill but want to get permission to use it before I post it up.

 
 

If you can help with more information about this Light Show we would love to hear from you.
