What?!?!?!? Not 100 in the base set with parallel sets of red, green, pink, blue, orange, brown, silver, and gold? Sorry, Neil, that's a terrible plan. Wacky collectors will never warm to your idea
You neglected to mention wood, lumber, leather, lace, grass, bronze, red ludlow, black ludlow, green ludlow, tan backs, white backs, autographed, sepia, printing plates, chrome, refractors, black, canvas black, rubber, craquelure, impressionist, cubist, plastic, coloring book, stained glass, pixelated, sandpaper, black & white, thermal, stone, super-sized, water color, needlepoint, fish eye, aluminum foil, comic book, mosaic, and wrought iron.
Come to think of it, does anyone actually know how many different types of parallels have been issued over the years?
MUST COLLECT THEM ALL!
And speaking of parallels, look at these beauties I just received in the mail!
"Sepia"
"Thermal"
"X-Ray"
"Comic Book"
And my all-time-favorite, "Transparent!"
