Hi Jesus,

Thank you for contacting Mearto with your appraisal inquiry.
I can't find any artist named Delene but am confident - from the style of this painting - that it is European and mid 19th Century.
Based on the photos and information provided, and subject to examination, this is:

European School, mid 19th Century
Landscape watercolor, circa 1851
watercolor on cardstock
depicting two small figures in the foreground of a vast fantastical landcape
with indistinct graphite inscriptions verso, marked "Delene 51" lower left verso
4 by 6 inches
CONDITION: appears to be in generally good condition
PROVENANCE: purchased from an antiques dealer
$100-150*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
