Attractive Leaves, Squash

Question

I’m interested in growing squash (summer or winter, either) that has large, broad leaves — almost symetrical, with a circular depression going down to the stem. I fancy pressing a mature leaf onto a shaped sand pile, and then carefully pouring/placing sand-cement on it to make a leaf replica. I saw such large squash leaves in a Fine Gardening photo, but the squash variety wasn’t listed. Any suggestions? Thanks in advance for your expert help.

I am not quite certain it is the same plant, but they may have been picturing a birdhouse squash plant. They have lovely large leaves.
