I understand people trying to at least cover their costs on a project, but I’d agree that the price is Very high. High res pics of all the original toys To show the detail of the sculpts would be interesting, but even then $300 would be asking an awful lot.
For perspective (to me at least), this is worth what it costs. An outstanding presentation and a fascinating look at the birth of the franchise.
