This colossal poster is 75cm x 48cm, & the very decent transfer sheet is also unusually large; so all in all, this was an excellent promotion.
The only weakness is that it isn't immediately apparent where you're supposed to apply the transfers. The numbers on the wallchart, which correspond to those on the transfer sheet, are quite small, but in fairness that's really a feature rather than a bug, making it part of the game to locate & match the numbers.
