That's me and my other pastime. I perform as John Lennon in several Beatles tribute acts.
The production rules state you cannot inspect any cards until after purchase. I can't find anything in setup as to when you can inspect your initial hand. There is no explicit "setup sequence" but the rules are presented in the following order: select cadres, draw initial hand, start 1936 New Year. This would imply that you must setup your blocks first before drawing cards but you can view your hand before buying units and purchasing more cards in 1936. This is how we've been playing it but it's slightly ambiguous. Has there been any definitive clarification?
