I recently embarked on a fun and affordable new rainbow for my favorite player and main collecting interest, Matt Kemp. Panini put a spin on the printing plate with Progressions parallels - which are limited to just five copies per color - and come in Cyan, Magenta, Yellow, and Black.
I was able to secure the Cyan parallel for $3.99 shipped, and it's by far my favorite of the quartet. Blue just works so damn well on Dodgers' cardboard.
The Magenta Progressions "Plate" set me back $6 shipped and has a very Mother's Day feel to it even though the card it comes from hails from the Father's Day release Panini puts out every year.
Finally, the Yellow was had for $7 with free shipping. To have 75% of the rainbow in the books for $16.99 makes me quite the happy camper. If anyone comes across the Black /5, please let me know.
