One Artificial Tree, Three Christmas's

Following up on the last post regarding the artificial Christmas tree we got a few years after the pics from the last post were taken, here are 4 slides depicting various Naylors, and 3 Donellys, and the tree in question.
These, to my estimation are 3 different Christmas's, according to relative ages, position of tree and other furniture in the living room, and the appearance of the new 7th child, Little Boy.

(If he doesn't read my blog, i hope his ears are burning).

This first one is the earliest, i would guess it as '66 or '67, more likely '67. Notice the TV is on the end wall of the living room, and the tree is in the northeast corner.
And just look at all those presents. You'd think we were the Rockefellers. And always thrifty, gifts were neatly unwrapped, so paper could be saved for use next year.
This must have been either during the gift opening Christmas morning, since most gifts are still wrapped, or perhaps, at the traditional open one present on Christmas eve event.
Notice the shirt Dad is wearing. I still have that shirt.

It has onyx embellished snaps, instead of buttons.

This next one is a year or two later, '68ish i would say, Rob has put on a few inches, and Randy's hair is blonder, likely from having spent more time outside the summer before. The tree is again in the northeast corner of the living room, and Mother's first oil painting is on the east wall, moved over from the north wall, where it was in the last posts' pics.
Check out the 7up bottle, and Rob's way stylin' belt.

The next one i'm saying is likely to be '69, David has arrived in the picture, looking 2ish....isn't he cute? If only he had stayed that way. JAY/KAY!! The tree has moved to the southwest corner of the living room, as evidenced by the inclusion of the thermostat on the wall, in this scene. See how the present pile keeps growing each year? We were upwardly mobile poor! DEE-LUXE!!

This last one is the same Christmas as the one just before. How do i know? The position of the tree, the curio shelf, the little light-up church, and the pole lamp are all the same, and just below the curio shelf, in both shots, on the tree is a green light, and a red ball hanging below it.

This must be after Christmas, the presents are gone, Randy And I are likely wearing new shirts we got, and the Donelly's are over...probably Boxing Day i would think. And funny little Davey is pointing at his Mom, thinking, 'hey you, camera lady, what you doing'.
