In an post for petro for sale with prices, someone posted a few items. One item had printed on it OIHOS another had SOHIO, again I missing something?

One more thing. Years ago I had one of the Gene & Glenn puzzles, where it is I don't remember. How about you guys who have one post the pictures of them here to see how many SOHIO made available?

No hurry, just to give each other more info to remember.
