Telegraph stamps are stamps intended solely for the prepayment of telegraph fees.
In most countries, the cost of sending a telegram was paid using normal postage stamps. These can often be identified by their distinctive telegraphic cancels or punched holes. In some countries and at some times, special telegraph stamps were produced or postage or revenue stamps overprinted to pay the fee.
The Costa Rican telegraph stamps were introduced in the year 1907. A set of very attractive eight postage stamps showing a steam train in a landscape was issued with different denominations and colours.
