Hi Bob -- well, they're maybe alike in only the vaguest sense. We're not that familiar with the Sportflics issues, but from what we can see,
it looks like Sportflics are more akin to the 1970 MLB Promo "hologram" cards from Kellogg cereals -- soft plastic finish over the top of
multiple images or something.
The Monster Magic Action cards are much more primitive. Unless you have the "Magic Lens" transparent hard plastic slab, the cards just look
exactly like what you see in the scans (they're 3.5 x 2.5", by the way, on slightly thinner cardstock than most '60s baseball cards) --
some distinct images with lots of indistinct horizontal lines. When you move the "lens" over the image, the ultra-thin, closely-bunched ribs
in the "lens" distort some of those lines on the card, partially obscuring some of the lines while highlighting others, which sort of rearranges
the poses and action. Monster eyes roll back and forth, wings and fins flap, puny humans flail helplessly. So in the vaguest sense of how
the images "move," they're almost more akin to the Push-Pull cards.
Not sure how many different cards were produced -- we've got an even dozen different images.
They seem like something that would've come out of Japan originally...
