83 Topps UV reactive backs
 

Finally got a pic of one of the other backs that reacts to UV.

Not anywhere near as spectacular as the 91s, but 83 Topps does react to shortwave UV.
It wasn't all that easy to get a picture of, mostly because I'm down to my weaker UV light.

The card at the top reacts with an orange glow, the one at the bottom does not. This should affect the entire set.

It seems images may not come through for everyone?

This is a direct link to the picture. Which works on my browser, but then, the picture inserting looks like it works from my end too....
