Wondering about the value of personalized photos versus the value of just autographed photos. I have numerous photos, mostly press/publicity photos that my late brother had acquired thru his job - a music writer for numerous newspapers and his own website. I have a stack for maybe 35 not personalized and a stack of maybe 50 personalized. Wondering what you folks think the difference in value would be, as I plan on selling all, individually ? I would think they would be of more value without being personalized, but would there be a large difference you think ?
