alright thanks for your awsners guys, personally photo size isnt a factor to me at all, the only advantage to smaller items is that they dont take as much space up as larger photos.

Honestly, if I were to buy an auto I would probably want a 8x10 not a 4x6 so it makes sense others would as well

Photo size is definitely one of the factors used to determine the value/selling price of an autograph. Any dealer will charge a higher price for an 8x10, compared to a 4x6. It's basically a case of 'bigger is better'.

ok i know this is a very stupid qusteion probally, but at a few places i buy autographs from sell 8x10s for quite a bit more then any other photo size which kinda makes sense. but now this doesent , anyway the autograph store at the mall i shop at, their selling a lauren graham 8x10 for 40 dollars plus tax but the dual 4x6 of her and alexis bledel is going for a few dollars less. im wondering why would one autograph just because photo size is bigger why is worth more then 2 autographs on a smaller photo. in reality is photo size that much of a difference or is the person runnning the store just clueless about autographs?
