The LP 35 anniversary sets of congas and bongos were a "special issue" of the regular LP classic fiberglass congas and bongos. The special thing with these congas/bongos was their shell/outside treatment which was the same as the top of the line Galaxy fiberglass congas and bongos: the sparkle on these congas/bongos was light blue with grey, and a commemorative badge. I believe these anniversary congas /bongos were issued in 1998-1999. (Besides the "sparkle" they do no share anything with the Galaxy models, Patato based conga and kevlar inside shell, etc).
When they first came out, here in Puerto Rico at the local distributor, they had them for a good price. The whole set of quinto, conga and tumba for $999 and the bongos for around $250. Yes, they were a limited edition. LP never said how many were built. If they sold well or not, I do not know. I did see Jimmy Morales, a famous conguero in the salsa genre, with a set of them and a few others.
If you want to get a history of it, contact LP customer service via e-mail at LP's web site. (

I think you had a good deal based on the original prices.
Enjoy your bongos.....
