Narrative:

Ground push-back from gate commenced with clearance from only one of two entities in fine print on airport chart. Due to division of tasks/workload between captain/first officer in the cockpit; poor non-typical and somewhat convoluted signage. Procedures annotated in fine print on the commercial chart; along with dealing with a new airport location; an aircraft swap and running late; a communication error was made between crew members and ramp/ground control; to where a potential conflict could have occurred. Captain was communicating with the ground crew and flight attendants; while first officer was communicating with ATC and running the checklist. Captain was assured a push clearance had been obtained; and push was commenced. However; only ramp control had given a clearance and not ground control as well. No harm done; but issue could be avoided perhaps in the future if there was some better signage on the gates stating that clearance must be received from both ramp and ground. Also better notes in bolder print be placed on the main airport diagram page of the commercial charts stating this requirement. Also perhaps overlap the cockpit tasking when it comes to getting push clearances so there are no communication errors.
