As a photography junkie I’ve long been fascinated with the way that three-dimensional imaging has paralleled the history of the medium from the early stereographs through the Viewmaster toys I grew up with (and which my son still played with in his preschool).
That baseball cards have multiple examples in these genre* is fantastic. But it’s the application of lenticular printing to baseball cards in the late 60s with the 1968 Topps 3D release followed by the run of Kelloggs cards starting in 1970 which is particularly awesome.
Between the Kelloggs 3D cards in the 1970s and 1980s Sportflics magic motion cards, I’ve found myself developing a specific weakness to lenticular baseball cards and their low-tech magic.
I’m not explicitly chasing sets of these but they’ll always turn my head and getting samples of all the different sets* is something I’m enjoying doing. I only have a couple samples of 1970s Kelloggs so far but each and every one is a joy to get and hold and look at.
*Well besides the 1968 Topps 3D sets which is just insanely expensive.
Most of the time I’m able to keep things in-line with my main collecting interests but this is not always the case. For example, last summer Topps released an On Demand 3D set. I normally ignore their on demand offerings since even the nice ones seem to only feature the same handful of teams and players. Plus they rely a ton on design reuse but usually do an even worse job of executing the old designs than Heritage does.
Lenticular 3D though? Of course I bought a pack. I wasn’t expecting to wait quite as long as I did but they finally arrived the week before Thanksgiving.
It was awesome. While it would’ve been nice to get some Giants I’m not even upset that I got Cutch as a Yankee. They look great in hand and I’m kind of regretting not buying more than one pack. The only disappointment (and it’s a small disappointment not a major critique) is that the action cards only show two frames of movement.
I haven’t had a ton of experience with lenticular 3D cards and the ones I do have are kind of fragile due to the all-to-common cracking issues caused by aging plastic and differing rates of expansion due to the way paper reacts to ambient humidity and temperature much more than plastic does. So this is the first time I’ve had a chance to take a really good look at them.
One obvious note to make compared to the older cards is that the current 3D cards depict action and the 3D effect works really well on pictures where the pose has considerable depth to it. I really like the Carlos Martinez for this reason and even in an animated gif it pops.
I hadn’t thought much about the physics of the lenticular effect before either but making these gifs made me realize that the lenses have to go up and down in order to create the stereo effect. While tilting the card is the only way to get the impression in a gif, the vertical lenses split the image into two. As a result, each eye sees a slightly different picture and your brain assembles the result in 3D.
Which means that I’m surprised and impressed that Topps printed horizontal cards in this set since that means they had to do two distinct print and finishing runs in order to accommodate the two designs.
Of course this also means that I’m a little confused by the choice to do action with vertical lenses since every other lenticular action card I have has horizontal lenses and has to be tilted up and down for the effect. From Sportflics to Topps Screenplays, they’re all animated with vertical movement. The current Topps action cards are the first lenticular action ones I’ve seen that get tilted left/right instead.
As I think about it, tilting up and down for action makes a lot of sense since you don’t want to confuse the eyes with combining two distinct action images into single still image. Which may be why the current action cards feature only two frames. Any more frames and your brain will try and combine adjacent frames into a 3D image instead of seeing things as action.
Note: that all the motion holograms I’ve see have been left/right tilt—suggesting that our eyes/brains process them differently than lenticular images. And I guess that makes sense too since holograms are 3D no matter what angle you view them at.
