(x) "901" giant address number of Eames Office - hand drawn {Stephen}

Just watched a short film on Charles and Ray Eames' Venice design studio, and noticed some great type specimens. Anyone have any idea what this one is?


I think this might be Helvetica Compressed/Inserat.

The geometrically strict lines on the '901' make me feel it was done by hand specifically for that size. It was their giant address number, after all.
