I have a metal Mobile Pegasus sign that is fairly large and would like to sell it. Trouble is, I have been told it is a pricey sign to buy, therefore I should investigate what it is worth. The sign is not flat, but like 3d. Where should I look?

Found a pic on the internet of what I have.

FROM WHAT I KNOW -IF THIS IS THE 3'
PEGASUS AND IS IN 8 COND OR BETTER, THE PRICE COULD COMMAND A NICE $1,500 OR BETTER! GO EITHER WAY BASED ON CONDITION. IF YOU NEED ME TO POST PICTURES, SO THAT OTHERS CAN REPLY - LET ME KNOW. BE AWARE THAT SELLING THIS PEGASUS
IS NOT ALLOWED IN GENERAL PETROLIANA DISCUSSION AND SHOULD BE POSTED IN THE FOR SALE AREA. $4 A PHOTO WITHIN THE AD. ADS RUN FOR 100 DAYS.
ARE YOU CLOSE TO DES MOINES? THERE'S A SHOW THERE IN EARLY AUGUST (CHECK EVENTS ON HOME PAGE)....YOU COULD SELL IT THERE(?)
HOPE THIS HELPS!

I have placed the horse on eBay. I listed it as a 36" wide horse, but from front hoof tip to tail tip, it is 48". From hoof to wing tip it is 38".

My item number is: 3688072593

I probably should have listed it here, but these things are not my specialty.
