toyarchive.com is just the place you need to go if you want to explore those toy lines you gushed over be it the 70's, 80's, or 90's.
It includes many of the popular, and even somewhat forgotten, toy lines that made people's childhoods so unique. Pictures and descriptions are provided for each toy line. As a knowledge base, finding that particular toy or toy line that faceted you as a kid is made easy. It certainly helped me rediscover a particular toy line my brother and I had forgotten in name, but knew by aesthetic.
You can also purchase toys from the site. However, this review is incomplete as I cannot comment on that experience.
Overall, it's a nice database. It may have a primitive layout, but it gets the job done. Where shopping is concerned, I'll have to leave that to another individual to comment. Otherwise -- check them out if you're interested in those ye-old toys of decades past.
