If you believe an organization should or does give a 100% or even 90% acurate historical record then you have a false belief and thus keeping that belief makes you deluded and surprised and upset by it.
Is not Aikido as put forth by the Aikikai a product and should we not expect truth in product labeling much as we do with anything we buy off the shelf? I understand the buyer beware approach and that we all should be looking hard at what we "buy" though I think that changing photos in this instance is an effort to mislead and to disassociate from the past where it is very likely we would never have the resources to find it on our own. In the political world it doesn't take many "altered" photos to get one on the outside. Should we expect less from an organization that is suppose to be the avatar of a product that is based on love, world peace and whose practice is spiritual in nature?
Just go straight.......
