Long-term reuse: saving toys for the next generation

My mom saved a ton of toys from my 70's childhood, and now my children play with them:

This is just a small sampling. (Check out the hair on the Sunshine Family. Nice.) My brother has a bunch, too: more Fisher-Price, some Playmobil, Legos, his entire Star Wars collection and metal Tonka trucks, and his boys play with these. I really love having these toys now, but it's incredible to think about Mom storing them for so long and then moving them across the country when she relocated to Portland four years ago.

I look at the modern-day toys my kids have received and try to imagine boxing them up and storing them for my grandchildren (and who knows whether I'll have any!). I'm sad to say that I never really bought or encouraged relatives to buy wooden, Montessori-type toys that have an heirloom quality. A lot of plastic has come in and out of this house. I mean, it's possible that modern-day Fisher-Price Little People might have the same vintage appeal that the ones from the 70's do (after all, modern-day toys will be vintage one day). It's just hard to see it now, and I shudder at the thought of saving them. Maybe I'll pick a handful of their most beloved toys for keeping, vintage appeal be damned. I have a few years to think about it.

Do you plan to save some toys for the next generation (or just for pure sentimental reasons)? Boxes and boxes, or just a few special ones?
