Thank you for submitting your item for appraisal. This appears to be a parlor rocker manufactured by the Larkin factory, just as you said. The original advertising is a nice addition but unforturnately does not help to increase the value. Rocking chairs are surprisingly inexpensive today. This particular by Larkin sold at auction within in the price range stated. "Asking prices" in the trade can be higher and vary. Some new colour might not be a bad idea at all.
