I have no connection to this auction and don't know the vendor, but I thought it would be a service to post for anyone interested. There is an Ebay auction purporting to be selling an original Eichler Brochure (for Marin County, I think) and Architect's Checklist.
If you're interested, it's listed as:
Original Eichler Brochure and Architect's Checklist
Item number: 7001727274
