Unknow Packages

Hello,
Hope you can help me out.
I've got some packages on my inventory that I have no idea what games are in it.
Wanted to make giveaways using those but I'm stuck.
Is the anyplace where we can check the games on those packages ?
As some are very old, maybe were already removed from steam but maybe the games didn't and as all are gifts they can still be redeemed.
Packages are:
26399
27013
109208

Got some more that I know what they are and have clues on the games in it:

31590 - Hitman Absolution DLC Collection
15357 - Sniper Elite + Sniper Elite V2
2574 - Action Indie Pack (Rip Trilogy, Rip 2 Strike Back, Rip 3 The Last Hero,SpaceTrader Merchant Marine, Penguins Arena Sedna's World, Larva Mortus, Tank Universal)
74582 - Art Appreciation Pack (Howler, Morphopolis,Gravilon).

Thanks in advance
