Maybe donate them to your local retirement community library...I have a good friend in his 80's,and I made his day by sending him the last issue of which he said brought tears to his eyes esp. the Cuba article..Mind you this coming from someone from Liverpool who worked the Ships in WW11 and gambled in Cuba before settling down in NJ and FL.
You never know if someone may be interested,but in this case,I knew for sure.
BTW,my friend's first trip to Vegas with his wife,brought back 2 sets of Holiday International cic's $1/$5/$25 from where they stayed and he found them and gave to me after all those years.Also remembered that a flood in the basement of thier NJ home destroyed all the matchbooks/etc his wife collected from LV/AC...
