Thank you, that sounds like good recommendations. I already wrote the Eames Foundation, the people who manage the house as a Museum today. I Think they are mostly ancestors of the Eames and really liked it, so they will show it on Facebook (they don't post anything currently, to leave more room for 'Black life matters'. Find that remarkable, by the way). That made me very proud, but I guess the impact in the number of supporters will be limited, as creating an Account is a big hurdle.
Still you are right, I probably underestimated the effect of the Facebook groups, I'll give it a try. Thanx again.
