DISRAELI DOCUMENTS
If you like 1960s graphic style, then this is the instruction book for you. It has everything, the blocks of bright colour, the repeating geometric shapes - Mary Quant could have used some of the pages as wall-paper. Another Czech design masterpiece.
I particularly like the page (scan 4) that exhorts you to forgo the use of the battered hammer and knackered chisel.
The Favorit PWB (1st style) derailleur features on scan 6 and scan 7.
