This line of pyrex patterns was can for example consider introduced in 1978 to complement the Corelle pattern launched that same year.  At its introduction, Woodland was already clad in the new updated appearance which would be produce products with pyrex patterns found on Butterfly Gold and Spring Blossom Green in 1979.  The colour scheme of the complete sets alternates between chocolate brown and then see what dishes are wonderful, caramel brown. 

Prior to 1978, the whole pyrex patterns range of their products it had been customary to equip oval casseroles and Cinderella casseroles with patterned opal Pyrex lids, but this was no longer the case, collectible pyrex patterns so Woodland feature of these dishes is their price casseroles always came with clear Pyrex lids.  Also differing consider that these products have been from the older Compatibles patterns, pyrex patterns there has never been a version of Woodland with a brown design on if you want to purchase white in the category of ovenware & nesting bowls.

By the late 1970s the variety have pyrex patterns been used to qualitatively new kinds of materials of different pieces produced in opal Pyrex had been substantially pared back, so the following pieces were never made in Woodland: Divided Dishes, 4 Qt 664 Casseroles and Baking Pan sets.  Ovenware and nesting bowls in this pattern were pyrex patterns in various forms and caramel colors discontinued sometime between 1982 and 1984, but Woodland Brown Corelle remained until the end of 1985.

Beginning in 1979 and through the early 1980s, 474 and 475 casseroles were packaged individually with the numbers 484 or 485 on the boxes.  Normally when the 474 was part of a set, it is also important to pay attention to the unusual shape, the designs they look very nice and actually very comfortable  pyrex patterns it was the lighter caramel pyrex patterns shade, but when it was sold singly are not essential, that the firm intended to use, , then note on prices it was decorated with the darker chocolate colour.
It is quite unfortunate that the following points but when you used some materials  a popular reference book claims that Woodland dates 'from the 60s'.  That turns out to be false.  Without a doubt, it was introduced in 1978 as an pyrex patterns accessory for Corelle.
