When companies cease to exist, assets are always dealt with in one way or another. As I recall, in the U.K., bankruptcy places those assets in the hands of the official receiver, dissolution transfers those assets to the crown (although they should have been sold or otherwise transferred before dissolution), and if the company is renamed, sold or starts in a new direction the assets remain with the company. I am not aware of any way in which a company can cease to exist without its assets being technically owned by someone or something.

Are there any clues on the photograph itself (agency codes, short abbreviations?). Whoever registers companies wherever this one was (or is) based is another good place to look; they should have records of companies which have been dissolved, made bankrupt of otherwise ceased to trade; along with lists of previous names. Try to contact them to see the current status and name of that company; and if not, to obtain the details of the last named company officers. Expect to pay a small but reasonable fee.
