This vintage bubble set has a couple slight variations. The one shown has "Gold Medal Bubble Set" on the box cover and two children blowing bubbles. This set came with two bubble pipes, two straws, a bubble dish, and a paper that says, "Making fascinating rainbow bubbles with a Gold Medal Bubble Set."
I have another with an box that is identical except it does not say "Gold Medal" on the box top. It does say, "No. 31, Mfg. by Transogram, New York." This set includes a bubble pipe, two straws, a bubble dish, a flat wooden spoon, and a small cloth. It also has a 2.5" bar of soap shaped like a turtle. This amber (or perhaps gold?) colored turtle says on its underside, "Gold Medal Bubble Set made by Transogram."
