Hi all. I am going through some new material and I found these Cuban stamps. Does anyone know where I can find any info on these? I do not have a book with Cuba in it. Any and all input is appreciated. I thank you in advance. NOTE: GIRO means.... General Interbank Recurring Order (GIRO) is an automated electronic payment service which allows you to make monthly payment to the billing organization (BO) from your bank account directly. The amount will be deducted from your DBS or POSB account and paid to your BO every month, upon the BO's request. That is today's meaning of it. I am guessing it was a similar way of doing business back in the 1800's/1900's, but you had to contact the bank to make the payment for you..... Not sure how it worked.
