No space for a desktop model, but you'd still like a model of your favourite aircraft? Perhaps you can find some wall space instead? 

Aviation Model Art displays your aircraft in an attractive wall mounted presentation.  The pictures below show a number of 1/72 scale aircraft displayed in A3 and A4 sized frames. 

Prices vary depending on kit availability ( as some are limited production runs ), and also aircraft and colour scheme complexity, but start around £85.00 plus shipping.
