Snakes and Ladders
Trumptonalia.
Snakes & Ladders board game by Topsail Games.

In the 60's and 70's simple games like Snakes & Ladders were still very much a part of nearly every kids' toy cv.

Which is why it's something of a surprise that this particular Camberwick example is proving to be quite elusive.
And why I only have a photo of the board so far.

But I do know that it came with one die [dice],one plastic cup to act as a shaker and 16 small,round plastic counters - 4 each in blue,red,green and yellow.

And the box dimensions are approx. 27cm x 21cm x 4cm.

No confirmation of the exact date yet though.But it definitely won't be any later than mid 70's.
