The museum concentrates on their history in the mid "Valley" area. It has a lot of cool artifacts that were from the city of Weslaco, information on the military heroes from around the area, and more information on the fathers who founded the city of Weslaco and surrounding area.
The Weslaco Museum also exhibits art. The best part about it is that the art is for sale! The asking price for the art was very reasonable. Admission to the museum varies. At the time I went it was $4.00 per adult and $2.00 for people under 17 years of age. For more information on current exhibitions you should give them a ring.
