This group has moved!
Monster In My Pocket says:
This group is abandoned, and has been replaced by a new group. The administrator of this group joined Flickr, uploaded 77 photos, and created this group all on the same day: April 18, 2009. Apparently he hasn't been back since then -- almost six years ago. I've messaged him but have never received a reply. The problem is that only admins can invite pictures to a group, and only existing admins can promote members to replace them as new admins. Therefore nobody can invite any pictures whatsoever to this group. Thus I eventually created a replacement group: www.flickr.com/groups/vintage_space_toys/. Please join the new group, and please post your pictures there instead.
