My absolute favorite Pyrex of all!  It's called Spirograph, came out in 1970.  The top has a blue and green spirograph pattern but what I most like about the piece is its lime green under-plate!  These under-plates just finish off the Pyrex pieces - I think.  But, the deal is, they're hard to find.  It's plastic and marked Pyrex but they seem to get lost somehow very easily...

I also have two other Pyrex pieces that had under-plates - the Nouveau Floral which has a brown wood-grain under-plate and the Moon Deco with a black under-plate.  All three of these happen to be the  2 1/2 quart size, number 475.

Isn't that the most amazing top?  The colors are fabulous together.

Thanks for dropping by.  As soon as I find the other pictures I took of the Noveau and Moon Deco, I'll post them...
