Vintage Mystery Undeveloped 35mm Film Rolls x 2

Lot of 2 Mystery 35mm undeveloped film rolls. There are two options to choose from, one lot of two has both color rolls, and the other lot of 2 has both black & white film rolls. We only have found a date on the one B&W roll of film that came inside its box, and is dated December 1974. Keep in mind, there are no guarantees that the expired film / undeveloped film will produce images, but that's part of the thrill & dice roll!  Since we found this at an estate sale we have no idea what are on these rolls....but that's part of the fun!
