Observe

- Watermark: a picture of the guanaco and the face value “20” are made visible when holding up the bill against the light.

- Security thread: a strip in paper money containing number “$20” and the BCRA acronym repeatedly and alternatingly is visible when held up against the light. It may be read partially on the obverse and the reverse side.

- Offset printing: an iris effect background.

- See-through register: half of the guanaco's footprint printed on the obverse side fits exactly with the other half of the image on the reverse side.

- Intaglio printing: a picture of the guanaco, main flowers, texts, numbers, animal’s silhouette, “XX” and the code for the visually impaired stand out in relief.

- Latent image: the initials RA within the image of a guanaco become visible when the bill is held horizontally at eye level and to the light.

- Marks for the visually impaired: the code below the animal's silhouette and the value in roman numbers “XX” stand out in relief.

- Microprinting: the repetition of the legend “$20BCRA...” at the bottom of the guanaco's silhouette and the acronym “BCRA” within the “20” face value may only be observed through a magnifying glass, given their tiny letter size.

Reverse

- Serigraph printing: wide strip with floral motif and the face value “20” in a pinkish-colored iridescent ink.

- Series: it starts with letter A. The vertical series is in red color and the horizontal one in black, with variable-sized digits.
