A few thoughts, I'm curious where this leads........ sort of like something neat found on Storage Wars.
1. Those initials are Y. P. , as best I remember my cursive lessons from the early 70's.
2. Earning a gold in July, this person was skiing an event in South America? Portillo? (if anyone has event results database to search)
3. Is that definitely an alpine ski sportube? (I'm not familiar with sportube sizes), otherwise could it have carried a water ski? Golf clubs? Would then make more sense for the July date if this came from North America. There are water skiing competitions.
OK, enough time wasted on that .......
