1. Passport Error

Page 17: Should be Central African Republic in English.
Page 18: Colombia mis-spelt as Columbia.
Page 22: The blue circle should be larger.

Page 42: Should be El Salvador.

myfdc 
Can we get this passport at the exhibition? I would only be able to go on thr 6dec, do you think i can still get all the MS?
p/s: 1st timer for this event
Sure there are plenty of passports. All free. You get it during registration.
All the MS should still be there as well as all the 6 cancellations plus one cachet.
You probably need the whole day as there is quite a lot to cover.
Enjoy!
