i see that some one on e-bay are pre selling a master run of the eagerly awaited mars attacks.
they say they are including the auto card of which they say there are only 10 produced ?
how can they be sure of getting a one or are there other methods of getting hold of it befor the box`s are produced ?

Hello and thanks for your question . Here are the stated odds:
-5 Lenticular Motion Cards (1:8 Packs)
- Green bordered (1:3 packs )
- Silver bordered (1:24)
- Gold bordered (1:101)
- 1/1 Printing Plates: 4 colors per subject: u, Magenta, Yellow & Black (1:1259)220 total
-Len Brown Autograph Cards –Gold Foil Stamped and Numbered 550 Total (1:504)

Approx. Print Run of Hobby
1443 Hobby Cases / 11544 Boxes/ 277056 Packs

I will have 30 cases on wednesday ...5760 packs... there are 10 of each base card that is foiled,signed and hand numbered each out of 10, so 10 x 55 cards equals 550 total autogrpahed cards in HOBBY boxes. Based on odds I should get 10 of these autogrpaph cards. Could get more could get less but feel pretty darn safe pre-selling 1 ;-)

i must be reading things wrong ,the pre sell seems to say 1 of 10 autos as if there are only 10 available in total? thats why i questioned the pre sale.if there are 550 great more chance of me getting 1 .

No worries, I changed the wording as I can see where it might be misunderstood. There are a total of 50 of each gold parallel card ...2750 in total, 10 of each autographed parallel card...550 in total and 4 unique printing plates for each base card ... 220 in total. the gold cards,autograph cards and printing plates are ONLY found in Hobby boxes.

viperdays is correct. Len Brown signed 10 of each of the original 55 and hand numbered each subject 1 thru 10.
