She is beautiful. Unfortunately Hollywood is well down in price from where she used to be. Personally I would be tempted to hold on to her until she bumps back up again.
By herself she is a $30 pony right now. Plus her ribbon and her comb she should be $45-46. The issue could be the repro wings. Although to buy them by themselves you could be $20 I dont always think they add $20 of value to the pony. However if it was me I would not sell her for less than the $70 mark and just hold out until she does.
