On 20 April, 1885, the American Bank Note Company entered the Ecuador order for 100,000 domestic 2c post cards, and 200,000 UPU 3c post cards.
A die for each value was engraved and then transferred 18 on and then 12 on to form a stone of 30 images. The cards were lithographed on card stock (22 x 28 inches, 140 lbs) from Hastings & Todd.
The printing was completed by 16 June 1885 when Ecuador was billed.
The Ecuadorian agent involved was named "Ruiz".
