Hi all, from previous posts I realise that there aren't many (if any) here that collect anything from Guyana but need help with finding out more about postal slogans from Guyana.
Here is one example of what I'm talking about;

I have others such as "Fire Prevention Week", "The Post Office Savings Bank Pays You 3% Interest Up To $25000" I am looking for more examples as well as I have several part slogans that I can't identify.
As far as I can make out these slogans were only used in the 1950's to 1960's or at least that is all I have found so far.
Any help would be very useful
thank you
