From Wikipedia:
The Baja Marimba Band was an American musical group led by marimba player Julius Wechter. Formed by producer Herb Alpert after his own Tijuana Brass, the Baja Marimba Band outlasted the Tijuana Brass by several years in part due to TV producer Chuck Barris, who included the group's music on his game shows in the 1970s.

The group would appear on stage dressed in sombreros and old clothes, with fake mustaches, smoking cigars, and drinking beer, all of which was regarded as humorously exaggerated Mexican stereotypes. The group appeared in goofy group photos on their album covers, stylishly created by Peter Whorf Graphics, and added a comedic allure.
A prime example of such a goofy group photo can be found on the cover of this album, with all members having their watch out. Watch Out! was released in 1966 on A&M Records (established in 1962 by Herb Alpert and Jerry Moss). The font in use probably is Victory. This phototype revival of Victoria (Flinsch, before 1900) was made by Lettergraphics shortly before. A decade later, Freda Sack would do a looser interpretation for Letraset’s dry transfer range under the name Victorian.
