A is for Archive - "Dyna-Mo"

Back in the days before glossy consumer-oriented catalogues, you had to buy the modelling press to find the after-market companies, write to them (enclosing a stamped, self-addressed envelope) and hopefully hear back from them, replies which usually arrived about four months after you'd given-up all hope!

In this case, Dyna-Model sent the potential customer a post-card sized flyer, with artwork from their own advertisements in the model railroad press, which as they have credited the magazine, must be artwork wholly or partially 'got-up' by the magazine! Further, the card . . . isn't; it's actually the same glossy sugar-paper as the original magazines and may have been provided by the magazine as a kind of reversed advertising?

The mailed owner has subsequently added the next item issued; R-23 (a sow and piglets), dating the flyer to soon after the magazine ad's had run so probably the autumn of 1947, or 71 years ago!

The owners of DMP have thought to tantalise the applicant with news of new products, by hand, on the back of the flyer . . . but then not actually listed them!
